65DartCharger/Dartman. I never gave that a consideration. Would AC have an effect on only one side? I do not know! California car, parked at the beach, always parked with the same side to the surf? Possible? Did the car's history show it was owned close to the ocean? I am curious why one side is sick, and the other side not. Some sort of chemical...possibly. Hmmmm. sgrip65
