ProStar AC/Heater Blower Motor acting up?

[Waterloo]

There is that harness recall. I'll see if I can dig up the part number, it is has an inline resistor. Solved most of my issues with the blower motor. Also replace the 30 amp breaker with a 30 amp regular fuse. Check the fuse box where that Blower Motor fuse plugs in for any signs of high heat. Pretty common on these ProStars.

Then, try to find where your Ambient Air Temperature sending unit is, the thermometer part. It will be in one of three places... In the driver side mirror or in the wiring harness buried under the radiator or back under your fifth wheel. It has a tiny bulb on it with two wires and a small bracket/clip. Dig that thing out and put it up high, like on the cowl where your wiper blades are. Trust me on this one, get that thing exposed to mother nature. Until I did that I would only have AC for maybe an hour or two and then the it would just blow hot air... Thousands of dollars later, I dug that damn thing out from under my radiator and attached it to the cowl and I have not had any issues with my AC in a couple of months!

I'll see if I can find the post on that service bulletin regarding the harness fix.
