Interior lighting problems on 91 Buick Park Avenue.?
Car is put into reverse, the overhead map lights come on. When the doors are opened, only the lights under the dash and the rear reading lamps come on. Rear reading lamps will not operate by the on/off switch. Overhead map lights do. Illuminated entry operates the interior lights same as opening a door, with exception that the door lock halo which operates also. Car has lamp monitor which lights up all lights on the left side plus one light on the right side. These lamps will flash for a minute or so upon starting the car. All of the other gadgets seem to work fine. I have checked a few of the grounds and found no problems. Any suggestions?
these cars have a single ground plate with most of the grounds for the interior behind the kick panel on the driver side about an inch up from the floorboard it is a common problem in areas with snow for this plate to corrode and lose its ground causing multiple problems at one time. find it, clean it, and your problems should go away. good luck
