Either your window switches are bad or the motors are.
The same exact thing happened on my 92 and I just finished fixing it. There are separate ground wires between the front and rear windows. Your ground is probably bad, mine had actually broken in half in the rubber boot in between the door and the body of the car.
Because the master control on the drivers door has separate areas for all windows. Start by checking power feeds at the drivers door switch.
Probably a ground problem. Find the common ground for the lights.
The most likely problem is warped rotors. Have rotors turned or replaced. Replace front brake pads.
Usually it is the O2 sensor
old fuel filter
it would be in the relay box under the hood
That would be a timing chain for this car.
If it's a 6 cylinder , 6 , if 8 cylinder , which I think Buick does not make in that model , it would be 8 .
Try checking your circuit breakers largefuses or relay switches for front power windows.
i have a 1996 buick century just came back from mechanic head gasket is gone and there is anti freeze in my oil i guess if you had water in your rad then you would have water in your oil.
Bad fan clutch!!
I have a shimmy or small vibration while driving the interstate on my 1994 buick lesabre - if i was to check the front and rear bearings - how would i do that and what would i look for
mabye the O2 sensors
A '98 Buick Regal, as with other cars, has a different size of speaker for the front and back. The front speaker size would be 5 1/4 inches, and the rear is 6 inches by 9 inches.?æ
I have a 1990 Buick Century 3300. Just replace the Fuel Pressure Regulator. It was leaking gas. Replace the vacum lines to the Fuel Pressure Regulator but I still smell gas inside on the driver's side compartment. The smell goes away when opening the windows. Where would there be a fuel leak that would cause the raw gas smell inside the car but not outside of the car?
always look in your owners manual. but I've driven and maintained a 90 91 93 buick century. if 6 cylinder i would suggest 4.4 litres or oil and change the oil filter at every oil change.
Do you have a picture on how to change the hearter core for this car?? If so would you send it to me.
You may want to check the thermal flasher.
four and a half to five, but I would put in four and a half and check it.
i have a 1976 buick regal century body has minor rust on bottom clearcoating is kinda flaking, the engine runs beautiful only 82,500 miles what would be the value
The most obvious answer would be a broken hose which need to be checked.
I would start with the Pickup Coil and the Crank Sensor.
It could be the heater core leaking.
The light is on because there is a fault in the system. It would be best to have the professionals take a look at it.
