My arrows in my mirrors,rear amber and front amber lights flash at random, and no I don't have the fob in my pocket.Also the headlight chime went off when the lights were not on and the door was closed.The only way it would stop was to lock the door with the fob Also the CD won't work and it won't come out.The time on the clock was way out.Any ideas? The dealer fixed a no cluster light problem, and the wink but its back.

Interesting..last week, on a Sunday, I was at a local GMC dealership and thought I saw one of the 2500HD trucks amber turn signals flash. It was a Sunday and the dealership was closed yet I thought maybe someone was messing with me. There was nobody around and noone in the truck! It did it again a few times. I figured the truck was saying, "hey, check me out..buy ME!". ):h Sounds like some kind of electrical gremlin. I don't recall ever reading about this in the forums as of yet!

big problem with these, lots of talk about it on the GM forums... I thought they said turn signal flasher module

I'll second that.
The turn signal flasher module is the problem with the flickering lights. There have been numerous cases of trucks flashing randomly in the lot and on the transport trucks.
