I seem to be having some strange electrical problems on an 88 Chevy Silverado pickup. The most troublesome one being the heater/AC control unit. It flickers and turns on and off, and is not working much at all now. The power locks stopped working and the wipers sometimes will not shut off. I thought maybe the heater/AC control unit was gone, so I got a rebuilt unit and put it in. Same problem, it flickers, and turns on and off, etc. Has anybody had this problem? or have any idea what could be causing it?
thanks, - Paul
