83 Fleetwood climate control issues
 

Hello all I'm having issues with the climate control system on my '83 Fleetwood (hearse). I managed to finally get my blower motor working but the motor will stay on the entire time the ignition key is in the on position, even when the climate control switch is off. Yet, it will not cycle in any other position other than the floor ducts and it does not change temperature (only flows outside temperature) if anyone knows where to start to fix this issue I need to take care of this soon as possible before the winter weather comes into play I had to use a tealight candle as my defroster last year.
