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

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!!

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.

The crankshaft sensor is bad,or the ignition module,one of the two.

Antilock brake light stays on


Start with checking the sensors on each wheel.  These will be the electrical wires that come from behind each wheel.  Also check that the tire pressure in each tire is the same.  Next, check your brake fluid level.
Sorry...that's all I can help you with.  Maybe someone else can help you from here.

94 buick lesabre brake light stays on and the bell rings constant


i'm thinking the emergency brake lever is down just a bit. try lifting it up when it does it to see if it shuts off. or maybe the float in the brake fluid res. is faulty. maybe try unplugging the wire at res. level sensor.
