I have a 1987 with manual a/c controls. I just purchased a new blower motor resistor and my fan still only blows on high. I know it bypasses the switch knob for the high speed. Also, I have about 14V at the plug on the resistor and across the resistor itself on all speeds.
Is it possible that the switch itself is bad? a pain to get out. Also, I just recharged my a/c system, but still no A/c. Gonna have to take that to a shop.
