I'm working on a 1990 chevy for a friend, It has the electric heater control head, the screen on it shows one of the little arrows on it but that is all, so it does have power, but none of the controls on it do anything, and the blower motor in the truck is constantly on, I'd say somewhere...
I am very seriously considering buying an ATT for my truck, but i want a reflash at the same time, i'm currious weather the kojo tune or the heath for the att is a better tune to run with it.
