:bounce2: My dad has a 98 chevy silverdo and the A/C and heater has problemes turning on. He will twist the dial, and nothing will happen. :flipoff2: the only way to turn it on is to beat the heck out of the air little black box under the dash. (black, rectangle box.) Does anyone know whats causing that/ how to fix it???
