Yeah, what he said lol. My neighbor has a 98 Malibu and I think he has the same problem...let us know if Venom'* suggested method works, I might be able to go over and fix his problem!
My mechanic (the one that does the work I can't...) is across the street from my office...I saw the same Malibu in his garage for 8 business days, while they traced an electrical problem. I couldn't believe it! Just think of how much money that would cost!
Good luck though, hope you get it fixed!
