I'm having this exact problem in my new S10, here in Brazil. The car is brand new. I give up to bring to the dealership. Here in Brazil they don't solve any problem, and the quality of service is terrible. I don't think is a loose or corroted ground wire, becouse the car is brand new. What a piece of crap, I will never buy gm again.
