How do you take the stock stereo out of an 01 Alero?

the first thing you'll need to do is to pry up the shiter display, disconnect the light and the ETS button. Apply praking brake, key in the ignition, foot on brake, move shifter into 1st gear. Gently lift shifter up and to the left. It will get caught on the radio trim, but will move with some gentle persuasion.

the radio trim has several clips that hold it in place. Start at the bottom and gently pull on the trim. you may have to gently rock it side to side as you pull.

Once the trim is free you will have to disconnect the heat/AC controls. if you choose not to disconnect them, turn the trim on it's side.

The radio will have 3 bolts holding it in. Does your radio have the THEFTLOCK system? If so, look in your manual for instructions on what to do.

The system prevents your radio from being installed in another car. If it is the display will say LOCKED!

How do you turn off the 'change oil' light in a 1992 Chevrolet Corvette Lt-1?

also try to change the oil.

Try disconnecting the batery for 15 minutes. The computer will reset itself. This worked on a '95 Thunderbird.

To reset the oil light, put the key in the ignition and turn to accessory setting (but do not start the car) Push the English/Metric button twice and then push and hold the "Gauges" button. The "Change Oil" light will flash for about 15-20 seconds and then go out. Release the button and turn key off.

When you turn the key back on, the light should be out. If it is not, repeat the above steps.

Try changing the freaking oil!!!!!!!! That might help!!! I'm just saying!!!!!

Fuel Filters
Oldsmobile Alero

Where is the fuel filter located and how do you replace it on a 2001 Oldsmobile Alero?

The fuel filter is under the car, directly behind the gas tank. It is between the tank and the charcoal filter assembly, which looks like a rectangular black box. The filter sits parallel to the back of the fuel tank and looks like a metallic or black cylinder about 2 inches in diameter and about 3 inches long. Use jack stands or a lift to give yourself safe and ample room get to it.

DANGER: The fuel system is pressurized! Before doing any service, relieve the pressure by starting the engine and removing the fuel pump fuse or relay while the engine is running, the car should die after a few moments. Also, it's probably advisable to remove the gas cap and disconnect the battery after depressurizing the system(make sure you know your radio's theft-lock code before disconnecting the battery!).

You should EXPECT gas to spill when you do this so keep rags handy - keep clear of open flames.

THINK before you work with fuel - a drop light with an open bulb is a bad idea, as is working indoors near a gas heater with a pilot light. If you have to be told not to smoke you probably should go to a mechanic (umm, for the car)

Before service, clean the lines and filter - use compressed air or carb cleaner.

The OEM unit probably has a METAL clip on the incoming line - it's very difficult to remove without a tool which is cheap and readily available at auto parts stores. Make sure the new filter comes with a plastic clip and don't try to re-use the metal one.

To remove the outgoing side of the filter you should use TWO wrenches, a larger open end wrench to hold the filter body steady and a flare-nut wrench on the fuel line. Failure to use 2 wrenches as I describe can easily result in twisting of the fuel line. Failure to use the flare-nut wrench can result in rounding the edges of the nut. The outgoing line has an o-ring which you really should replace if you are replacing the filter.

When the lines are off remove the bracket on the side of the filter.

New filter installation should be reverse of the above.

How do you reset the security light in your 2001 Oldsmobile Alero?

== == The repair below is a theft password relearn procedure. It may get your car to start for a while, but does not repair the problem. The most common cause for this problem is the PASSLOCK ignition cylinder. It may need to be replace, then re-learned again.- TechJK -------------------------------------- Turn the key to the on position for about 30mins. After the first 10 minutes the security light starts to blink. Then it turns solid again after another 10 minutes. The last 10 minutes is to reset the passlock system (you can leave it on for longer to make sure you reset it). Now take the key out and try to start the car. I had to do this when my car was not starting; the fuel pump was off because of my passlock system.

How do you remove and replace front wheel bearings on a 1996 Chevy Blazer 4x4?

you cannot replace the wheel bearings by themselves in a 4x4. they designed the hubs to have wheel bearings inside them. you must replace the whole hub assembly to get new wheel bearings. should run from 50-100 dollars a piece from a parts store, and about twice that at a dealer.

You need a 36mm socket and a breaker bar . Take the spline nut off the end of the cv shaft. I suggest doing this with the wheel still on the ground. Then jack the truck up. Remove the caliper and rotor, take out the three bolts holding in the hub. Be careful around the abs sensor. They are expensive. Installation is the reverse of removal. Torqe the spline nut to approx 180 ft.lbs.

How do you reset the maintenance light for oil changes on a 2007 Toyota 4Runner?

Turn the 4Runner on, make sure that you are looking at the "odometer" miles and not the "Trip" miles. Turn the 4Runner off, hold the "reset" button, turn the 4Runner On and the "MAINT" light will blink 3 times. Release the "reset" button and the light will turn off.

This worked great for me but the light flashed 5 times then went off. 2007 SR5 4WD 16,000 miles recently purchased from dealer hopefully there is nothing else wrong/ FYI the manual told me that the maint light is for oil change.

How do you reset the sensor light after you change the O2 sensor?

If the car is an 87 Pulsar, the reset switch is under the kick panel (Plastic between the bottem of the dash board & the floorboard) on the drivers side. Take this panel off & the switch is a push button on the metal box. Push the button & check the sensor light. The sensor light may also meen it's time to replace the timing belt. Don't ask how I know this.

  1. 3 of 4

by: Bobby

from: AutoWhiz.com relayi am not sure they have a relay for the horn on that one.. i thought that the circuit has a horn, a fuse, then the steering wheel sliding contact, then the airbag.. usually when they stop working, its the horn wire right behind the drivers airbag, it pops out of its connector.Add a message posted: 2004-02-25 01:16:23

On the '96 Sunfire the horn relay is located under the dash behind the glove box. I was able to get to it by removing a small plastic plate held by three screws and reaching up and to the [passenger door] side under/behind the glove box.

What would cause a squeaking noise coming from the drivers side wheel but not the brakes when you put the car into gear?

There can be two possibilities. The first is your wheel bearing going bad. The second could be the drive axle wearing out.

YOU HAVE TO TAKE THE HOUSING OFF WHERE THE COIL PACK IS RIHJT ON TOP OF THE MOTOR You have to take the four bolts off the top of the engine. (Where it says 2.4 liter) Lift up the top and the boots will often come up as well. The plugs are in the center after you took the top off. There are no wires connected to them.

Check Engine Light

Dodge Ram Van
Oldsmobile Alero

How do you clear error codes?

Depending on the year of the vechile you can clear error codes several different ways. If the vechile is pre 95 you can disconnect power to the battery for ten minutes and that will clear the stored codes. If the vechile is post 95 you have to have a scanner hooked up to clear the codes. 96 and up there is a hand scanner that can be purchased at your local parts store so you can scan and remove the code.

my 2 centsThis is more than needed but I am trying to give a broader explanation. The " check engine light" is by far one of the most misunderstood technological advances It is a warning light that is illuminated when there is a problem affecting the EMISSIONS of the vehicle.. Don't let it bother you as it is a good thing once you understand it. One point that was brought up a recent meeting of technicians was that the amount of hydrocarbons is greater when the gas cap is left off than when the engine is running. Hydrocarbons are part of pollution emitted as gasoline evaporates. Going a step farther, one facet of the emission system is the "Evaporative" portion. This is when the fumes from the gasoline are leaking from the system into the outside air. This is one part of the emission system that can trigger a check engine light. I would say a small percentage of the vehicles that have a check engine light are the result of a loose or inadequate gas cap. But understand that many scenarios are possible with the "check engine light" The vehicle's powertrain computer (note that some vehicles have multiple computers aside from the powertain computer) will run a series of self-tests. They will only run under certain criteria. And they are different from manufacturer to manufacturer. Some self-tests or �monitors� are not run until preceding ones have run successfully. So if there is a problem in one particular area that is preventing another self test from running, you can have a situation where one problem is fixed, but another still exists. If you fix a problem and drive the car through a drive cycle that sets the monitor (or self test) the light will go off as it passes that criteria that triggered it in the first place. There are many different sources for the light to come on. Anything that caused combustion to fail, commonly called a misfire will set the light. Various sensors such as oxygen sensors that evaluate the exhaust before and after the gases are burned in the converter. Transmission codes may set the check engine light to appear. If the car is running okay, get it fixed in a reasonable amount of time such as within the month. It will probably save you fuel if you do. However if the Check engine light is flashing, you should be driving it as damage is being done to the converter. Some emission components are covered beyond the standard warranty. The converter for example is covered up to 80,000 miles by the manufacturer. After 1996, the auto industry went to a idea called OBD II (on board diagnostics). This was to get all the manufacturers onto a similar plane for troubleshooting and powertrain control. While they still differ, many corrections and adaptations were made for technicians to better fix the check engine light problems. Prior to this there were so many different and poor troubleshooting data from a check engine light problem that resolving the problem was much more difficult. Many early warning light of this nature were set to illuminate based on mileage. An Oxygen sensor was one of the things that were meant to be replaced when that mileage was hit. This is much like many current "Change oil lights� that are set based on a pre-set mileage. To start testing for the check engine light, you�ll need to find the codes from the computer, match the code to the troubleshooting procedure, follow the procedure to find the source. Repair the source, light will go out if that was the only problem. There are "monitors" or self tests the computer runs the car through a drive cycle, if a problem occurs, it may not run all of the self tests until that problem is taken care. There are self-tests for the oxygen sensor circuit, egr system, evaporative system to name a few. Therefore, another problem may exist. It is emission related.

OR hook up a scanner that is capable of clearing codes, and hope that it won�t come back on. But don�t bet on it. Lastly, disconnecting the battery in some cars will clear the memory of the computer and may temporarily turn the light off. Beware that this may also cause other problems such as the car not rembering it�s idle and will have to relearn it, the radio may be rendered inoperative or in the case of the new Toyotas, the air bag can blow.

This Is an Addition to his answer.

He is trying to over explain.. Just undo your negative battery terminal for 30 minutes then re connect it. this should clear any fault codes. the exception is if there is still a problem then it wont work.

Car Starting Problems

Why would your car shut off while you were driving and it will not start or turn over?

I had a dodge omni that did that exact thing and it turned out to be a $15.00 part that was located under the distributor. I forgot the name of the part though. .

Answerthis same problem happened to me..i have yet to solve it tho. it was running, then it started running rough so i pulled over to take a look under the hood. It never did turn back on..(84 Toyota celica)

Well this happened to me, i ad to change the ignition module and it ran just fine

If it doesn't start or even turn over, I would suspect you have a dead battery possibly from an alternator that failed.

Oldsmobile Alero

How much do tires on a 2002 Oldsmobile alero cost?

I just bought a new tire for my Alero and I paid $90 at Wal- Mart. This did not include putting it back on my car. For a set it's $240 plus all the extra charges they add on. I think it ends up being like $300 after all is said and done at Wal- Mart. However my husband just bought new tires at Sam's club and they offer free repairs with their tires. 2 days after getting his new tires he got a nail in it and the repaired it for free. My suggestion is to look around and compare prices and see what you get for the price. My husband only paid $10 more for each of his tires than I did for mine and he got the warrenty.

How do you replace the fog lamp bulb on a 99 Alero?

Underneath the fog lamps you'll see the black plastic covering around the lamps, remove the screws that hold two together(no need to remove all screws), and slide your hand to the back of fog light. It's the kind of light that locks into place when you rotate it. Turn the light and slide the socket out. Once you've done that, remove bulb and put in new one and turn into position that secure it. It's easy if you jack the car up a little, but it's not necessary. Good luck

What a pain, I had to remove the bolt that holds the two pieces together as suggested, plus 2 along the side of the bumper and 1 closer to the middle of the larger piece in order to bend it down and fit my hand in.

To replace the foglight bulb, it's a lot easier to remove the headlight first. You will see two black tabs on the headlight, pull them straight up and wiggle the headlight to the front. Then the foglight will be right underneath. You won't have to get on the ground at all.

Why does the security feature of a 1999 Grand Am GT come on randomly and the car not start?

I own a 1999 Grand Am and when the security starts acting up like that it is a sign that the ignition is going out. I had to replace my whole ignition. What it is is that the key is coded and linked to the ignition and when it starts acting up it means its going out. So, get a new ignition....

hey, i have owned my 1999 for 4 years or more. you know what the problem is ur gas cap. if ur gas cap is not put on right (even if it is 3-4 days later) the light comes on. the only thing to do is wait it out or u can really wreck your car. just make sure ur gas cap is on tight and doesn't allow air in it and u should notice that the light doesn't come on at all or as much.

Hey Laura==Something is wrong with it and it takes a dealer to trouble shoot these. GoodluckJoe

yea i have taken it into the dealership many times! every time they claim to have fixed it. but it just keeps on happening.

My wife's 2002 Grand Am GT did the same thing tonight for the first time. The tow truck driver disconnected the battery to reset the security feature but did not work. He towed it home and said to leave the key in the acc position for 10 minutes and try starting the car....I tried this and it worked...don't know if this is a sign of things to come but hopefully next time it happens I will know what to do.



When I called the dealership about the security problem, they also told me to put the key in the ACC position and wait for it to stop blinking..now i just sit there with the car off til it stops blinking. It takes about 10minutes. But its really frustrating. My friend tried disconnecting my battery also but that did not work. The dealership also claims to have fixed it many times. And now its happening all over again and they want to "try" and fix it. its ridiculous!

I too have this same problem with my 2000 Grand Am. I thought I was the only one.Please if someone can help let us know!!

This has just happened to me. 2002 Gramd Am. I had it towed to the dealership and they informed me it was a computer chip that has failed. Charged me $400.

I work in a car audio and remote starter installation shop and see this many times. the reason the car will not start is because the pass lock system it has built into the car is designed to activate after a third attempt to start the car and it doesnt start. it then activates and for about ten minutes the car needs to be in the acc or ign (car dependant) position and wait for the light to stop blinking. I am unsure of the fix though.

I have actually experienced this many times on my 2000 Grand Am GT1. I have found out two things that may help solve this problem:

1) Get out of the car AS SOON AS the security system activates. I don't know why, but it always seems to cease faster when there isn't weight fluctuation in the car. Then proceed to close the door. (proceed to #2)

2) a) Hit LOCK once, then UNLOCK on your remote TWICE. b) If the security system does not cease, allow it to blare for about another minute. c) Proceed to hit LOCK once and UNLOCK 5-6 times. d) Wait approx. 30 seconds between repeating (c) as many times as needed for the system to stop blaring.

This has seemed to work with me about 3 times.

remove steering colum cover.. U should see a pair of wires going in the ignition switch...(where the key goes... yellow i think) turn car on using tips above and then disconnect... anit-theft light will go on and stay on... car will no longer stall or not start...

  • I have a 2001 grand am and my car has failed to start twice now. I kept the key in the acc position and after 10 minutes or so, it started. Also, when the car is stopped at a stop light, it seems to chug every once and a while. About every 10 seconds, it seems to want to die, but never does. I have cleaned the fuel injector, replaced the fuel filter, but it still is not enough. I want to do something, but I am not sure what to do. Any suggestions?
  • Your car might be leaking coolant through the engine some where (into one of the cylinders). I had a similar problem a couple of years ago. I think it cost me around 400-600 to fix :(

Mainly because the GM engineers did a really poor job of "great idea but poor real world follow-through". Both of my daughters have the Passlock problems in Gran Am's and we've solved them so far through information I got from the following URLS:




For instance, on the bulldogsecurity.com site, you can specify the make/model of the car and it will show you pictures of the wiring harness and how to get to it....ie 2002 Pontic GranAM

We ended up dis-abling the system via cutting the wire while running and have now been about six months on both cars with no "theft" dis-abling and sitting waiting for the system to re-start.

For what it is worth.....check out the above sites....

"Free to start everytime in Oklahoma once again...."


ok I'm a mechanic, and own a 00 grand am, when the security light comes on and stays on it means there is a problem with your anti-theft system. what that means is either the chip inside the key is faulty, the sensor inside the dash, or wheel where ever your key goes, or your BCM, body control module, is faulty. Most of witch are going to come and go. BE Warned, when it finally goes out your car will not start until the bad part is fixed because everyone doesn't run around with a GM code scanner and cant turn this feature off if it goes out. A temp fix is when you go to start your car and it cranks but wont start, 1 turn the car off, and try and restart with the key turned the opposite way( i know the key is same on both sides but at this point it will make a difference). if it doesn't start 2. leave the key in the on position for 10 min, this is telling the computer your not here to steal it, and resets the anti-theft, BCM, and dash. 3. after 10 min the blinking security light will go constant, than finally go out when it is finished. If the key is moved during this you will have to turn the car off and restart the 10 min reset. Now when you start your car you hope the light will be off this is good and means more than likely it's the key witch needs to be replaced, a cheep and quick fix. If the light stays on it could be 1 of many issues 99-03 were dark years for GM anti-theft, but I made my money from them lol I or at least gets you going till you can afford to get it fixed, from here on out while your doing this just leave 10 min earlier just in case I'm sure your boss will eventually get tired of hearing you have car trouble, and limit your stops because this happens randomly.
