    Blower fan will not blow when heat is switched to defrost.

    79 C20 A/C equipped. Blower fan works on all speeds when selector is on vent or heat. Blower runs only on low when switching to defrost. Vacuum lines are good. Blower switch is new. I'm not a 100% sure the AC compressor is good but all the wires are hooked up.
