instrument light dimmer problem.
Instrument lights go out when parking or headlights are turned on and the dimmer slider does not work, day time lighting work good. The photo cell thingy on the right hand switch panel DOES work when I put a flashlight on it the instrument lights come on and go back out when light is removed from it. I have replaced the headlight switch assembly, hoping for the easy fix, same symptoms wit NEW switch. All the lights work perfectly from the light switch, just instrument lights go out when lights are turned on. I dropped the panel under the dash and discovered a remote control alarm system had been installed some time in the past, I got it completely removed now and plan to replace the dimmer thingy under there next. I suppose if that does not work I will just jumper the photo cell and have bright instrument lights all the time. Got the oil temperature gauge working by cleaning around the sender and cleaning the connector, I will replace the temperature gauge sender on the right head next week and hope that fixes the coolant temperature gauge, if I short the wire to the head coolant temperature gauge goes up to max reading so I believe it is definitely the sender. The car is GREAT except for these few electrical gremlins and I got is for a decent price, just seems any car I purchase spends a month in the garage. I also have a totally dependable (today) 87 Fiero GT that spent two weeks in the garage a year ago after I purchased it. Got the gremlins out of it at that time and it has performed relentlessly since then. I am 72 and this under dash work is getting tougher to do, wish I were rich and could get NEW vehicles and hire out the work but that is life and I am still here to do it at a slower pace. Thanks for all the replies and help from you guys,
