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.
