Is there a blower motor relay on the AC equipped models of the Skylark in 1964 and 1965 and if so, where is it located?
Thanks!

Thank you for the schematic! Very useful. As I read this, there does not appear to be a relay for this circuit, rather a resistorized blower (fan) switch which appears to route energized current from the battery via the ignition switch and the fuse box to the blower motor. I got to thinking about your input on the reason the AC suddenly stops blowing no matter what the fan is set on and then a few moments later appears to work fine again. As the engine RPM is increased, could the R134a charged compressor and system, originally designed for lower pressures with R12 reach enough pressure to force the compressor clutch to kick off? If that was the case, the blower motor would still operate and not shut completely off..correct??
