I just recently purchase a 96' Lumina with a 6 cyl. 3.1l. I can't get any light on the dash, theres a short of some sort, but no idea where to start. Secondly, when the headlights are turned on, the clock on the radio unit goes blank? For some reason the engine coolant well seems to have emptied itself over the process of a 2 week period? I ran the car in park for 30-40 minutes and couldn't see any sign of external leakage? Any ideas? Any feedback would be greatly appreciated.
