Front Blower Heater motor went out, the AC part but back blower works for heat only, any thoughts out there for fixing?

My heater has stopped working. not getting hot or cold air

The van lives in the Bahamas. Found the "blown" thermal resister fuse behind the glovebox. No replacement fuse or complete thermal control piece on the island. Will replace in States next month but this inconvenience is really a PIA.

The fan motor simply will not respond when you turn the switch on. It had worked perfectly up to that point. Can feel heat/cool air coming thru vents after a while, but there is nothing to force it into the passenger compartment. Looking for a solution. Will post if and when found.
