I have a 90'' LeSabre. The lights in the guage cluster went out. Not all of them went out though. Only the bottom lights went out, the ones that light the gas guage, speedometer, and gear selector. I took the dash apart and checked the lights and they all looked good. The fuse is good. Also the gas guage isn''t accurate, it jumps around alot but can give me a general reading but not accurate at all. Does anyone know if there''s something wrong with it or if i have to get a new guage cluster?
