1990 Buick Century Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 1990 Buick Century

One or more power window switch may fail. The affected window may work intermittently before failing completely.

A door window may move slowly or stop in mid travel due to a failing power window motor. The affected window may start working again after the motor cools off. Replacing the faulty window motor will commonly correct this concern.

A coolant leak may develop from the water pump. The engine may overheat as a result of the coolant loss. A leaking water pump should be replaced.

It was hers but the water pump went out and then she just used it to store hay and feed the horses from the trunk. I got it for $50, towed it home and slapped a water pump in it and it has been running since. I got it at ...

I bought my 90 Buick Century about 6 months ago. It passed hands many many times and was not well maintained. It was in 2 accidents before I owned it and when I bought it I was mostly just crossing my fingers that it would last more than a month.
