I have read the various posts regarding what to look for. Can someone
tell me if this is possible...My son just purchased the car. Previous
owner stated he changed the compressor and since the system was low on
freon the blower motor will not work. Not on heat or AC. Are we still
looking at the power module/ blower or is it a relationship to freon
The blower motor is controlled by BCM (body control module)and the
control panel setting. Depending on circumstances a signal is sent from
the BCM to the power module which is then configured to the speed called
for in the motor. If the motor isn't working, it may be faulty/faulty
control module/bad or corroded connections/wiring. Check for trouble
codes in the BCM (F codes) for a possible clue. It's pretty-much a
detective job with something like this.
