I own a 2003 Chevrolet 1500hd 4x4. It has heated seats which tend to come on by its self and will not turn off. The seats get extremely hot. Since this problem occurred, I'm now getting a service 4 wheel drive light, but the 4x4 seems ok. I think the short in the seats is effecting other parts on my truck.
