Hi All, I have a recently purchased '02 Fleetwood Bounder 39R diesel pusher. I have noticed that the thermostat seems to be difficult to control. Running a series of tests, one thing I figured out is that while Zone 1 runs the Front A/C unit (Main Salon) and Zone 2 runs the Rear A/C unit (Bedroom) oddly if I blow a hairdryer on the sensor in the main salon, the rear A/C unit turns on. Likewise, if I blow the hairdryer on the thermostat itself, which is located near the bedroom of the vehicle, the front A/C unit turns on. I haven't found a wiring diagram, yet, but I am wondering if anyone has seen anything like this and knows what's going on or how to rewire it?
