Why would all electrical work but the engine not turn over?
I had this happen twice on my Honda Odyssey, once it was the ignition switch (under the dash behind the key slot), and the second time it was the starter. I would get the starter checked before you start replacing parts. Most auto zones and advance auto parts stores have a testing bench for starters.
Where is the radio amplifier relay located on 2000 Chevy Tahoe z71?
It's located underneath the front passenger seat.
What size capacitor you need for a 1000 watts amplifier?
It takes 1 farad for every 1000 watts so u need 2 farads.
What cable do you need to hook up your mp3 player to the cars stereo?
For the 2002 and similar models, connect an audio cable to the small socket on the inside left wall of the glove box. Depending on the type of radio you have, you will need to go into the radio menu and select AUX input.
Where do the 2 wires go from the little white plug on the alternator on a 82 Suburban 350?
A 95 LeSabre, with the factory alternator, would typically have one larger wire to the back of the unit, then a regulator plug on the side. The large wire is the battery connection, and is usually connected, using a fusible link, to the battery connection at the starter. The regulator connection I couldn't say for sure without the wiring diagram for the vehicle, but usually one wire always has voltage, and the other has voltage when the ignition key is turned on.
Why the abs light comes on in your chrysler 300 1999?
The ABS light is on because the ABS module detects something is wrong with the system. It will remain on until it is fixed. As long as the light is on the ABS system will not function if needed. Take it to a trusted garage for diagnoses.
How much does it cost to get the key fob reprogrammed?
It can cost as much as about 300 dollars to re-key the average car. This varies depending on the type of ignition and the type of key.
my 95 neon did the same thing check the ground wires in the trunk there are in the corners of the trunk next to the tail lights take them lose and sand the contact area.s that should fix your problem
How do you change rear turn signal on a 2003 chevy impala?
Remove the two phillips screws located directly under the turn signal assembly (standing in front of the vehicle, look just above the bumper). Slide the assembly forward, out of the vehicle body. Twist the bulb socket a quarter turn counterclockwise then remove the bulb assembly from the housing. Remove the bulb and replace it, then reverse the process.
Diode is a two terminal semicon. Diode is a Switching device
If the plastic post/window frame covers are felxible enough - or if there is a rubber trim piece, you can use a thin piece of plastic to pry the edge up and another thin piece to tuck the wire underneath, going just a inch or so at a time. Do not use a screwdriver or metal object like a scraper.
How diode can be used as switch?
No, a diode can rectify an AC signal but is not able to amplify an AC signal. Diodes are two layer devices whereas transistors have three. It is this very thin 'base' region in the transistor that gives it the ability to give a voltage or current gain.

What is the Wiring diagram for pioneer deh-16?
It should be color coordinated. There should be 4 of 2 set wires (8 wire together) for the speakers. Each set should be the same color except one is the color with a stripe. That tells you the positive and negative cables going to the speakers. Then after you wire the harness to the speakers, connect the Battery and Remote lines.
What are the negative effects of a light bulb?
Regular light bulbs work as heaters while giving light.
More than half the power used by Incandescent Bulbs goes to heating your room, rather than lighting it.
Most household electricity supplies come from rainwater flowing downhill (Hydroelectricity), or boiling water to drive steam turbines with coal, oil or nuclear heaters.
Fluorescent lights emit a narrower range of light wavelengths, using their input power more efficiently.
LED lights emit on an even narrower range of light, so are brighter within their colour.
Lasers can be even more efficient, but they are often so focussed and one coloured that they are not very useful for household lighting.
How do you change a 1999 buick century turn signal switch?
Remove the plastic covers around the steering column. Remove the panels by knees and feet on driver's side. You'll need a Torx bit to remove the Signal switch, follow the path and disconnect wire connectors. Retrace steps to install new switch. All in all, was pretty simple. ~Dawg
- The WD-40 squirted in the emergency flasher switch worked in my 97 ford mustang. Thanks so much for the info.
- Thanks for saving me the coins to pay a mechanic. I have a 97 Ford Van and the question fit my problem to the tee. The solution also fixed my problem.
- My wife push the flasher and that started all the problems. I took your advise and it worked for me too on my 1995 Grand Marquis. Thanks for your imput.
- I have a '99 Ford F-150 4.8 Liter V8, and this seems to have fixed the problem. It began as an intermittant problem and has gotten progressively worse over the past couple of months. I thought it was only affecting my turn signals, but I later discovered it also involved my brake lights. Moving the emergency flasher switch up and down a number of times solved the problem. Thank you!
- This also worked for me I have a 1999 Ford Expedition. I moved the hazardous lights up and down and the problem was solved.
- I thought I had checked the relevant fuses on my Ranger truck, but missed the one for brake-Emergency Flashers. My flashers were on - the button in the extended position when the fuse blew. Because the fuse went I didn't know the flasher was still in the on position. Therefore the turn signals and brake lights didn't work. It wasn't until I got the flasher in the off position that the turn signals started working again.
- hey it worked for me too! i almost brought her in to the vultures till i found this. thanks!!!!
- Worked on 1998 Lincon Continental...moved hazard warning switch in steering column up and down....worked great! THANKS!
- The WD40 worked like a charm. I have been trying to fix this problem for 2 hours. I sprayed WD40 and problem solved. Thanks so much.
- It works , don'ask me how , but it works.
- Just used WD4O on the hazard switch of a 97 Aerostar whose blinkers have not worked for months. The switch now works freely, and the blinkers work, too.
- I had a right front turn signal not working, sometimes. Then the left front stopped working, sometimes. Replaced lamps and still no joy. Tried the hazard flasher switch a few times and it started working but only sometimes. Sprayed WD40 into the hazard switch, exercised it a few times, and all OK now. Many thanks to the original poster.
- Good Morning! Let me echo the repair of the WD40. I had the same symtems of turn signals, flashers not working. Checked all the fuses. Went to Auto Zone to seek advise, They called FORD for me (really nice guys here in Warren, Pa) Ford pointed them/me to a light processcor that costs in excess of $200. A dealer only part) Auto Zone then suggested for me to access the web and seek out like problems which I did. Thank you to the original poster of this issue and Auto Zone. Several squirts and I worked the switch...and presto...everything started working again! No cost at all to fix this prob. I already has the WD40!
- It worked for me too on a 1997 Ford Thunderbird! Took me 2 days of checking things and not being able to use the care before I "Google'd" the problem. The Internet is great and so is your web site! You should have an option for people to pay something if you site helped them. This was worth at least $50 (and more if I would have taken it somewhere).
- Thank you VERY MUCH !!! The WD-40 solution worked GREAT !!!!!!!!!!!
- Thank you, worked for my 1997 F-150!
How do you change the high mount center brake light bulb in a 1996 Honda Accord?
From the inside of the engine bay, looking down on the headlight that needs the bulb, look at the back of the headlight, it should have a plastic ring where the bulb is held in place inside the headlight, turn this ring carefully to loosen it, then gently pull out the bulb socket and wiring connector, unsnap the plastic retaining clip from the wiring socket, and out comes the bulb.

Where is the Daytime Running Light Module specifically located for a 1994 Jeep Grand Cherokee?
The Daytime Running Lights module (DRL) is located behind and below the radio in all Gen 1 Neons (at least the Canadian versions). Remove the console faceplate by just pulling it off. Remove the Radio with a 10 mm socket. You may be able to continue without unplugging the radio, but it's easier to access if you do.
The DRL is bolted on an angle to the lower rear of where the radio sits. Two 10 mm bolts also hold it in place, you will be easily able to see the left hand one.. the right will be more difficult. Both can be accessed by inserting your 10 mm socket on and extension through the bolt access holes under the radio housing. Be careful not to lose the bolts when you've released them, as fishing them out from the shifter console will be annoying at best!
The DRL is connected by one large rectangular connector... it just unclips and pulls off. You will lose your daytime running lights and High Beam indicator once removed, however all other headlight functions will remain.
Resetting check engine light on Kia Sportage?
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. Therefore, another problem may exist. It is emission related. OR hook up a scanner that is capable of clearing codes, and hope that none are still active. Disconnecting the battery can create other headaches and will not likely solve your dilemma. Best bet is to contact the local snap-on dealer and have him refer you to a known good shop that specializes in this technology-he will know. The " check engine light" is by far one of the most misunderstood technological advances by the public. This is an needed in-depth understanding for the public. It is a warning light that is illuminated when there is a problem affecting the EMISSION SYSTEM only. Emission system being the pollution control system. Don't get a hard on against it as it is a good thing once you understand it. One point that was brought up a 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 that about 7% 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 17 different computers) will run a series of self-tests. They will only run under certain criteria. And they can be vastly different from manufacturer to manufacturer. Some self-tests 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. 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 vastly, 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
