Air conditioning gremlins
Hello and thanks again. Same car, 64 Skylark wagon originally AC equipped. During rebuild I replaced all the AC components including drier, condensor, evaporator, suction valve, lines, compressor and clutch. I did not replace the dash mounted blower switch but did replace blower motor/heater core. Wiring all looked good from stock harness.
Charged system with 134a and matching oil after evacuation. Blower switch is 3 speed and original as far as I can tell. AC works fine but you do have to gingerly move blower switch to maintain air flow. Driving along at 50 mph,fan on high suddenly AC turns off completely. Moved switch through all blower speeds and nothing... Turned down a side street, shut off fan switch and after a few minutes tried it again. Blower came back on and AC continued to blow as per normal. Switch? Relay? Other? Can't be a fuse since It came back on of its own accord. Thoughts? Thanks!
