When I got my 93 Suburban 3 months ago the dome lights worked on and off with alll the doors, then it quit working with the front 2 doors. It has one of those off/auto switches on the dome lights (under the headlight), at first I thought it was the problem but it works fine with the rear doors, so I thought it was the front door pin but they trigger the key in ignition buzzer. SO basicly the lights don't trigger with the front door switch but work off the other switches correctly. Any Ideas??
