FullTiming: At least your fans work. On our '87 the recirculating pump is located behind the front bumper on the passenger side. On ours the cold air when parked is because of 2 holes under the heater (just forward of the passenger side front tire). The pump in the driver's side bay is for the bay heater. Behind the heater control on the dash there are several small vacuum lines that control the vent defrost/heat. For your propane heater, ours won't ignite either and we are working on that one ourselves! Try the sail switch. I have the owners manual if you need a copy. And as for Dean's air leak, I would guess at the wipers. See if they work. The connection is above the ball.
