Five problems related to electrical system have been reported for the 1998 Buick Century. The most recently reported issues are listed below.
My vehicle's window controls and lock controls are no longer working, when locking the door or the window will go down but will not come up. The rest of the windows control throughout the car will not work as well. The lighting in the car flickers if you would push the lot or the window control. Anterior light is no longer working. None of this works even when parked or driving down the road.
Dash board light where the mileage shows. Cannot see anything, the light suddenly went out and cannot see miles on car. Also, automatic button to push seat back and forth is not working. I consider this a safety factor because the seat is pushed up to close to the front .
The vehicle experienced a problem with the gear shift due to a faulty electronic system problem.
Front day-time light/signal sockets are overheating and burning the plastic parts of socket & bulb. Replaced bulb+socket produced the same results within several weeks. Dealer does not want to investigate unless paid. Gm says car out of warranty. Burning smell was detected about two years ago but couldn't locate the source, only after the flasher failed. Bulb was still functioning but the electric contacts did not function.
In rainy weather conditions the windshield wipers became inoperable, cause unknown. In addition, while driving on highway vehicle went completely dead due to short in electrical system.
