How do you pop the hood on your 92 century when the cable is broken?

Your actually lucky on your car, the other cars in the Century family (Pontiac 6000, olds cutlass ciera, and Pontiac 6000) are quite a bit more involved to open there hoods.

The Buick century is the easiest car to open the hood on when the cable is broken. You will need a T15 or a T20 Torxdriver. You use this to take your grill off. Should be 4-8 screws holding it on. Once its off and out of the way, you can see the hood latch mechanism. You will be able to figure out how to get it to open from there.

Why did your horn honks 3 times when entering vehicle what does that mean and Why did lights flash 3 times when exiting vehicle another time?

I'm making an assumption on the year probably a 90 something. I usually means that the security was on and the vehicle alarm was tripped. This is to let you know the alarm was set off and reset itself while unattended.

What could cause a clicking noise while driving but stops when braking on a 1994 Buick Century?

if turning and your car clicks, check cv axles. if going straight, check brake pads for looseness in caliper bracket, check rotors for thickness and runout(warpage), check brake hardware, and especially caliper bolts and bracket bolts.

How do you change a starter on a 1993 buick century v6 3300?

Why wont 1998 Buick Century Custom start the engine rolls over and over but car wont start even backfires?

First check for fire at any of the sparkplugs and if you have spark then check your fuel pressure and if its not within specs then replace the pump.

What should you do if you are not getting any fire to the spark plugs in your 1993 Buick Century?

Really, there are many possible causes for this. When asking a question of this sort it is helpful to specify the engine size. Only generic answers can be provided when we don't know what car you have. Also, how do you know you aren't 'getting fire to' the spark plugs?

One thing I would suggest is disconnecting the plug wires at the coil end. If you crank the engine sparks should come out of the coils while cranking the engine. Do not touch the sparks as they feel somewhat unpleasant and can trigger heart attack.

If there is no spark at the coils, then proceed to check for blown fuses in every fuse panel.

Now see if you have one or more bad coils. If you disconnect the coil and put a test light between the two _primary_ electrical connections of the coil. While cranking the engine, the light should flash. If it does and the coil produces no spark, replace the coil.

The next thing to check would be the crank sensor. If you have a good crank sensor signal and no blown fuses, suspect a faulty ignition control module. The easiest way for a DIYer to check the module is to just replace the thing.

If the crank sensor and module are good and no fuses are blown, your next suspects are:

1) Car alarm.

2) Wiring fault.

3) Dead ECM/PCM.

== == I think your problem may be one similar to the one I had with my 1994 Ford Taurus. One of the wires between the ignition and the spark plugs may be damaged/loose/frayed/disconnected. It took my mechanics almost 4 full days to track and repair the problem. Additional Answer I am having the same problem. Here is the order I've done things...

First tested the fuel pressure, and then the firing at the spark plugs, and this showed me it was a fire issue and not a fuel issue. I then took my ICM, and coils to the local shop and they tested it on a computer and said there was nothing wrong with it. I proceeded to change the crank sensor because this was a part I couldn't test, and it was cheap. Once it was gapped properly the car started to run for a few minutes. I reattached the belt and soon afterward the engine quit again. No fire. I am going to the store tomorrow to drop the $96 for an Ignition Control Module, and I'm praying hard that it fixes the problem is possibly a sporadic 0% then 100% then 0% firing is because the ICM is feigning death. Please Jesus let this work... :)

How do you replace the ignition wires on a 1992 buick century?

Do them one at a time, matching length to new one. Try also to match routing of the wire on the engine. On a V6, the back three may require transfer of cylindrical metal shields on plug end from old wires. These back ones can be hard to remove, since they can be stuck on and not much space between the head and the firewall for leverage. Twist them on the spark plug to loosen first. Put a small dab of dielectric grease in each boot to aid removal the next time, which also protects against moisture.

Why might the dash and tail lights not work on a 1989 Buick Century?

Answer
it could be because one of your tail lights, brake lights, reverse lights, etc. the dash light goes off to let you know this. there is nothing wrong with the dash, probably. then again i have also seen minor electrical parts fried that cost an immense amount of mula. try the lights new answer
i hit a deer once and that same thing happenned to my '88 century. I ended up replacing a fuse in the dashboard fusebox that, in the manual that came with the car (if i remember correctly) did not directly correspond to either the dash lights or rear lights. only after checking ALL the fuses and after the replacement of this supposedly unrelated, yet obviously blown fuse, they worked.
My wife decided to jump start another vehicle during our ice storm and burned the contacts in the light switch.. which was the contact to bridge the dash/taillamps

New answer:
I had this same problem with my 1990 Century. All my lights worked (except dash/tail) and my fuses were good. Replacing the head light switch took care of the problem. I hope that helps

2001 Alero - What is the problem when your check vehicle light trac light and anti-lock light comes on at the same time. Dealer states a sensor but can't fine how to fix it. What do you suggest?

This sounds like your wheel hubs need replaced. These are where the sensors for ABS and Traction control are located. I'm very surprised a dealer would not be able to find this. It is possible another sensor is bad, but this is the same problem I had with my 2001 Alero.

If you have service engine light on, trac. off light and the ABS light on the same time, you may be able to get it fixed my reprogramming the power control module (with updated software calibration). Mine was fixed for free at a dealer under a recall campaign when GM called me yesterday.

How do you remove 1999 Buick Century Limited rear deck speakers that apparently are now defective because the bass is now buzzing with distortion in both?

I had the same problem on my 99 Century LTD which has the Concert Sound III sound system. I have replaced the speakers and can offer some help. To replace these speakers, you must remove the entire back seat and take off the rear shelf upholstery, which has the speaker covers/grilles attached to it. This isn't as hard as it sounds, It takes about half an hour, a helper, and some patience. Please DO NOT attempt to pry off the speaker grilles. They are not detachable and they break easily.To remove the seats you will need a flathead screwdriver, some pliers and/or vice grips, and a small "star" screwdriver.1.Start by removing the seat bottom. This is done by pulling on 2 release tabs (little black rings sticking out from under the seat, 1 on each side.) Pull on both of the rings simultaneously to release the seat.2. After removing the bottom you will see 2 brackets protruding from the bottom of the seat back. 2 nuts that are on studs hold the bottom of the seat back to the frame of the seat. After removing the nuts the seat back must be lifted up to unhook it from the slots in the frame. This is best done with an assistant.3.There are three black buttons/rivets that attach the rear shelf upholstery to the seat frame . Take these rivets out using a screwdriver/plier combo, and don't be afraid to get rough. Just get on both sides of that rivet with some pliers and pull it straight out. Save these for reassembly.3. Now, you can remove the upholstery by simply jimmying it out on both sides. The brake light will come with it, and there should be a wire that you can detach by clicking it out of its harness.4. The star tools comes into play to remove the speakers from underneath the decking. I found a small socket wrench with a star bit fit between the angle of the glass and the speaker itself.You're done! Be careful, and you should be fine. The first time me and a friend did this to replace one speaker, it took about 30 minutes to get the seat apart. The second time went a lot faster. Good luck!

I have the same exact problem in my 1999 Buick Regal LS. I know both of theses cars are almost exactly the same thing. I have a Monsoon sound system. I'm not sure if your car has the Concert sound system in it. I have looked all over my car and it seem that you have to remove the seats. So far I have noticed that the seats somehow slide into a bracket on the frame, but there also seems to be a bolt holding them in place. If I look inside my trunk, I can see my speakers and there seems to be a clip on the enclosure they are mounted to. None of that seems to help though unless you are able to get the rear dash off. If anyone else has a solution to this problem, it would be greatly appreciated.

The above directions were SOOOOOOOO helpful. Very accurate and help to make what could have been an all day project into an acceptable 1 hour project. Thank you.

In your 1994 Buick Century the radio-clock stays on when the car is turned off and if you take the fuse out for the radio the clock still stays on how can this be fixed?

Answer: I assume you mean the radio clock light stays on after you turn the key to the off position. Based on my research there are there are three things that can cause this.

First, there is the possibility of a bad diode in the radio itself which will require the replacing or disconnecting the radio.

Second, there is a short somewhere causing the clock to stay on. Finding such short can be a hassle and it might be easier simply to disconnect the clock then trying to find the short.

Finally, there is the (rare) possibility that the Body Control Module (BCM) has gone bad but this is unlikely if this is the only issue you are having.

Jordan drove from his home to his new college He drove 150 miles in 2.5 hours What was his average speed in miles per hour?

To get the answer, you would divide how many miles he drove by how long it took him to drive it. The information you need to set up your problem is 150 miles and 2.5 hours.

150 / 2.5 = 60

So Jordan drove an average of 60 miles per hour.
