Weird Problem?

porboy · July 31, 2009

The other day when I went to start my truck (2007 GMC Sierra 1500 NBS) the horn honked a couple times like I was trying to start it with the alarm on. I shut it off and re started it and no horn. I went to leave work and it did it again. Seems to happen after the truck has sat. I did not lock the doors last night with the FOB to see if that made a difference and when I fired it up this morning the horn honked twice. The honks are in rapid succession like someone is screwing with an armed vehicle. Has this happened to anybody else??

I just ran a bunch of errands and every time I start the truck now it sounds like the alarm is going to go off?????? I guess it is back to the dealership for more warranty work. Truck only has 12k on it. This is starting to get a little old.
