Hey all, still diagnosing but out of nowhere I have no power at my A/C compressor. Previously it would just run all the time and not shut off (so I’ve had it disconnected but it’s getting hot outside so I plugged it back in) but now it won’t engage my compressor.
I hit the compressor with 12v from the battery and it engages, tested the wire coming off the compressor and it’s showing no power. Checked under the dash, all the fuses are good, I tested both ends on the A/C Control switch (driver side near radio), 12v on each side. I haven’t tested the Thermostat Control Switch (passenger side) yet but I do have a new one I never installed - I believe I have to remove the dash blank panel above the glove box to access it? Do I have to take the heater box apart to replace it?
Thanks for any info in advance! It’s a 68’ Coupe with factory A/C -
