Flashing Headlights

Tfin · January 20, 2004

Has anyone seen their headlights flash on and off around 10 to 15 times all on their own with the engine off? I've seen this on two seperate occations. I just happend to be outside and looked at the front of the truck and the headlights would turn on and off by them selves.

The only thing similar between the two instances that I've seen this is that the remote entry device was within range of the truck. The doors don't lock and unlock, and the parking lights don't flash.....just the headlights.

Any ideas? Anyone?

I had that dryer installed per a GM TSB, that helps dry condensation out of the heat and a/c ducts. It kicks on at some determined time, and for a determined amount of time after you shut the truck off. I can't remember the times though. Occasionaly, the lights with flick on then off when it happens. You can also hear the heater fan blowing too.

I would have to agree with Mountaineer Tom.

Hmmmm, well thanks for the replys guys. I don't think I have the dryer MT spoke of. I haven't heard anything like that kicking on.

So I guess its off to the dealer for an excorsism then. I've only got 6000 miles left on the warrenty so I'll definately want to have it checked out before that ends.

Thanks
