Everything on the car works except for the heater motor. I removed all of the ac stuff, condenser, etc... I plugged in the purple wire and the black one to the motor and nothing happens, I checked the motor with voltage from the battery and it works, the vaccum lines are not hooked up an all i want is defrost. can anyone tell me which wires go where? and what i can do? thanks...

 

Take out the control head. Look at the "mode" switch. You'll find several wires on it. Find a brown one that leads up into the dash all by itself. Follow that wire about a foot up in there, and you will come to a connector of shockingly stupid design, which when you try to take it apart, you will discover it is burnt to ashes.

That wire is the supply to the whole A/C system; all fan current (except for high speed) goes through it, and the A/C compressor clutch current too. When it burns up, none of that works.

Cut both halves of it off, and replace it with a BIG THICK insulated slide terminal pair. Not yerbasic weenie little ones, get some big fat ones. There's alot of current there, and the small terminals will just burn up again.
