I've had this problem. Check the brake switch. It's located behind the black plastic shroud above the pedals and below the steering column. Pretty much dead center. Cheap and easy fix, just plug in a new one. They're about $12 from autozone, I think.

For the Brake light to stay on and the fluid is up...sounds like your sensor is playing dead......

For the battery to die after only (4) hours..you have a very big drain on the battery itself.....without the vehicle right here to look at would be very hard to even guess...electrical problems are a hands on chore...

I'd take it to your garage/mechainc

I have a 98 Buick Century and recently replaced the cluster gage with a newer year model used. But now my E brake light refuses to go out what could be the problem? Thanks.


Check your brake fluid reservoir it could be low.There is a fluid level sensor in the side of the reservoir and low fluid would make this light come on. .

91 Buick Century-About 75-80% of the time I will start my car the service engine light will stay on. It idles really high then when I put it in gear it sputters and almost always dies unless I give it lots...


Sounds like carbon build up on the ( IAC Valve ) idle air control valve. Take IAC valve off and get a can of non-chlronated brake cleaner and a wire brush and clean carbon out of valve.If this does'nt fix it take the mass air flow sensor off and do same but do'nt use wire brush just the cleaner.Afterwards reset the computer by taking the ground off the battery for 30 seconds or pull the ECM fuse out then put it back and this will reset the computer.HOPE THIS HELPS!!

Brake light just came on in 2002 buick century. Brakes work..could it just need brake fluid?


it could, that should be the first thing you check. If its low, the brakes may need service. as the brakes wear it takes up fluid, and the pads may be worn to the limits.

1996 Buick Century 6 cyl. The brake lights stay on after the ignition is turned off. Where is the brake light switch located and how do I remove it?


Hello

The break light switch is down under the dash. Follow the brake pedal up and your hand will hit it. Release the tabs and slowly pull the connector out and the lights should turn off.

have a great weekend.

My brake and anti brake lights stay on all the time


CHECK ALTERNATOR OUTPUT IT SHOULD BE 13.5 TO 14.5 VOLTS WITH ENGINE RUNNING.IF VOLTAGE LOWER 12 VOLTS THAT WILL CAUSE BRAKE AND ANTI LOCK BRAKE LIGHTS TO COME ON BECAUSE THAT NOT ENOUGH POWER FOR ABS BRAKES OPERATION.IF ALTERNATOR GOOD.BRAKE AND ABS LIGHTS ON ALSO MEANS LOW BRAKE FLUID LEVEL CHECK BRAKE FLUID LEVEL.ALSO. YOU HAVING BRAKE FAILURE.YOU NEED TO HAVE GARAGE OR DEALERSHIP CHECK BRAKES SYSTEM.BEFORE BRAKES COMPLETELY FAIL.
