The air conditioner blower motor works on directly on the battery supply where as the compressor works on the engine power so if you shout down the engine the compressor will stop but the blower will stop only you take out the key properly,

SOURCE: my 1995 jeep blower motor runs even after you shut

Unplug the relay and see if it shuts off. Or unplug and remove the blower resistor and see if a broken wire on the resistor is causeing a short to power.

Blower motor will not shut off


I can't speak to the cost, a local dealer can do that. As for the reason the fan runs on, it sounds like either a stuck power relay (location should be in the owners manual) or a bad fan speed regulator. Since the fan is stuck on high, I suspect the fan speed regulator is bad. On some cars the regulator is part of the fan assembly, and on some it's separate. Also, there is a possibility you can repair the circuit board, assuming it's something as simple as a burnt out diode. Best of luck!

2003 chevy avalance a/c blower moter runs with ignition shut off


If you have the automatic climate control and the blower motor won't shut off then you have a failing Blower motor speed control module. Something inside this module goes bad and the result is a blower motor that keeps running at times even though the engine is off and the key is out of the ignition. The module isn't repairable but has to be replaced. I believe it is located behind the passenger side of the dash panel.
