In our ’64 300K with FA/C, there are two fuses in the A/C system. The compressor clutch is fed from the 15-Amp ACC fuse while the three-speed blower is powered from its own 20-Amp HEAT-A/C fuse. Included in the blower speed circuit is a resistor under the hood on the cowl. The A/C clutch does not cycle but is engaged 100% of the time with ignition switch on and MAX COOL or FR COOL buttons are pressed. That seems like a step backward from efficiency but may be a result of problems with the thermostatic switch??
A recent post indicated the A/C control doors may be left in position by pulling back the FR COOL switch. The compressor will not operate but fresh air will be routed to the A/C ducts and vents.
Underhood wiring to the A/C clutch and blower speed resistor do not pass through the bulkhead connector but are routed through their own grommet on the firewall.

Are you guys referring to Factory AC?
