Do you have a diagram of the AC circuitry? Or a picture of the page of the shop manual?

This could be a can of worms, some vehicles will run 12v ign+ to the motor then feed the ground back through a resistor circuit (the rheostat) others will feed 12 volts to the rheostat and switch through to the motor with the motor grounded, other wise more modern vehicles use the climate control processor to do this, so tell us what vehicle, if it's US Mr. Idiot will know better than me. Thre point is you have to see what it's supposedly doing, PS have checked ALL the fuses?
