Hi folks:

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.

Thanks in advance.

When you say "still no AC"; have you checked to see if the compressor clutch is engaging?

Yes; send it to the repair shop.
