On my car the lights behind the gauges, when it was cold, had to wait for the car to warm up before they came on. Now that it's warm they turn on fairly quickly, but today it was raining and they didn't turn on at all. What's going on. I replaced the rheostat, but that wasn't the problem. Mechanic thinks its the GEM Module, but i don't want to spend $400 just to find out that that's not it. Please help




Dealer says they have to charge me for the labor regardless and they're $30 more per hour than this other mechanic. Is there anyway to test the GEM module to see if it's failed. Or bad. Or could i have a bare wire somewhere causing this, just seems weird that when it was raining today, the lights didn't work at all and they usually come on after a little while.
