    Thankfully, it stopped working after we got home from our most recent trip, not during!

    Anyway, the last night of camping, I turned the a/c down from high to low. On low, it worked, but had a buzzing sound that it's never had before. It bothered me, so I put it back on high and left it there.

    After we got home and set up to dry and clean, I went to put on the a/c and the fan isn't working. All settings (fan, heat, and a/c) have the buzzing noise. When I put it on either a/c setting, I can hear the compressor kick on.

    I am hoping it's just the capacitor (sp?) as that is a cheap an easy replacement. The buzzing sound has me concerned that it's the fan motor. I hope not, but still maybe cheaper than anything to do with the compressor.

    We have an ABS roof, so it's going to be a pain to work on the a/c from the top. And I'll have to finish cleaning in the heat and wait until it's dry enough to put it down before we check it out. Any advice would be greatly appreciated.

    I have never worked on these units, but it does sound like the fan motor is probably tight...

    It's a good thing to hear the compressor kick on. If you can get to the fan, try to spin it by hand and see if it will start for you. The start capacitor is usually pretty easy to replace. I've done the one on my home AC unit and it takes just a few minutes. Good Luck!

    Put boards down on the roof to support your weight when working on the unit

    Check for a dirt dobber nest. I have seen them build a nest on the fan and stop it from turning. However it sounds like there could be another problem but I would check that first as that is the cheap way :) either capacitor, bearings or windings

    Much ado about nothing, in fact "boards" would only damage the ABS surface which is curved. I installed a Carrier AirV A/C on my own Santa Fe so I spent quite a bit of time on the roof - it's a non-issue.
