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.
