My cruise control stopped working last year on my 2007 Silverade x-cab. I know the problem is in the brake switch because if I kick the brake pedal to the side a few times it will work until I stop (use the brakes) and then to get it to work you have to kick the pedal sideways again. Anyhow, at a yard sale yesterday I met a guy with a 2008 GMC Sierra with the same problem, and he told me he has to do the same thing (kick) to get his working. I just want to know if any of you others have the same problem and solution, maybe it's a manufacturing defect. My brakes are new, and the reservior is full. Truck has 80,000 miles and that's the only electrical problem except for the passenger window won't go down, the alternator failed, the rear speakers were lousy and have now totally failed, and the map light won't work on the passenger side.
