Folks,
Can anyone shed any light (pun intended) on an intermittent problem I'm having with my truck? When the truck was only a few weeks old this first appeared: With the lights on, the signals will both come on with the brake lights(this includes the mirrors). If you put the hazard lights on the high mount brake light, the brake lights, tail lights and the license plate lights all flash. If you use the turn signals one at a time they will flash once and stop with the lights (both sides) staying on weak. When it first happened it only lasted for part of the drive that night and never happened again until last night. I mentioned this to a GM tech friend of mine soon after the first time. He said he had not heard of any similar problems on other trucks, but if it reoccured to bring it in. The thing is, it goes away before I can bring it in. An electrical problem is difficult to diagnose if it doesn't exist at the time it is being looked at so I don't want to waste anyones time bringing it in until it persists.
Anyone seen this before? I'd like to get this resolved before I head out on a trip this coming weekend.
