When I tried starting my Charger for the first time last weekend, the GLHS computer that I had was bad. The vacuum solenoids went haywire, and the cooling fan came on. This was without even starting the car, just with the ignition to ON. So I know the fan at least works. But when I swapped in the GLHS computer from Ray's car, everything worked fine except the fan didn't come on when I unplugged the coolant sensor to set the timing. Fan works fine in his car though. Any ideas?
