Position 5 on my 2002 montana heater control does not work.
I have put up with the same problem until I found a solution today. For me, I believe it was a two part solution:
First, there is a 30 amp fuse (?) located in the passenger side fuse box (next to the door). I believe the fuse was labeled something similar to "HVAC Blower High". Looking at the box, it was the fuse in the very bottom-left position. This is not what I would call a bus fuse so I couldn't tell by looking at it that the fuse was bad. I first tried switching this fuse for the electronic window fuse. I was able to lower the driver's side window so I thought the fuse was good. However, it was not until after I completed step two (below) that I realized that I could not lower the passenger side window from the driver side control. I switched the two fuses back and the window controls worked fine. So, I replaced the suspect fuse and the problem was resolved.
Second, I read online this morning that a bad blower resistor could cause this problem. I also read that the part was fairly easy to replace on this model so I thought it was worth a try. I bought a replacement at my local dealer for $49. To install, I removed the bottom panel from the passenger side (right under the glove box) by pulling down on the three panel "screws". With the panel down, the heater blower was exposed. I found the resistor located just behind the blower. I unplugged the resistor from the blower as well as the wire harness located immediatly on the resistor. I then removed the resistor by removing the three (3) 5/16" bolts. The entire operation took about 20 minutes from open to close. ....the majority of that time was spent trying to get my big fingers around the bolts.
All 5 positions now work. ....Now if I could just resolve the problem with the windows frosting.
