Classic Auto Air #2 4/5/2024 SUCCESS!!!

Two, would be that it wouldn’t switch the AC system on until I put a small heater in the car.
Being an actual climate control system, it was already too cold for it to activate the AC.
Once it got to about 70 inside the car it came on and started blowing 40 degree air

Whoaa- Deja Vu!
I just went through this very issue today- could not get the compessor clutch to engage, no voltage coming out of the trigger wire on my under dash unit. Pulled the whole unit out and apart, only to discover that the control had a thermostatic coil on it; I cupped it in my hands and blew on it for a bit and it started passing current. Put everything back together, hit the unit for minute with a heat gun and it works perfectly. Just wasted an entire afternoon and accomplished nothing- other than learning something new about AC...
