Want this question answered?
The compressor is coming on because you have the heater set to defrost. Take it off defrost and the compressor will not come on. I would suspect the compressor is locked up.
Compressor not running?Heater control in heat position?
If the compressor will not come on at all, it is not because the system needs charging. Check for a blown fuse, disconnected wire at the compressor, or a defective compressor clutch.
As long as you have a heater strip installed on the compressor, you will not have a problem.
I repelaced the air conditioner compressor and the climate control unit. on the counsel, the compressor still reads, OFF and the air won't come on. is their a way to reset?
possible clogged or damaged heater core
heater fan broken.
The heater may not be on - but the fan still blows air through the vents when they're open !
If your heater is a heat pump , then yes.
The conclusion of and air compressor is a supply of air. The air compressor generates air that is stored in a tank.
Yes, it will run when in defrost or mix.
Running the AC compressor uses horsepower, and the truck does not have enough to overcome the loss.
