We picked up our 17 377 2 weeks ago and did a shake down trip last weekend. All went well except the rear ac unit would only run on low cool. Once switched to high cool unit shuts down. High fan setting didn't work either.
Service tech from my dealer came out to my home and replaced thermostat yesterday, unit worked fine for the 2 minutes we ran out. Just tried turning it on this afternoon and no high cool or high fan again.
We are leaving on Tuesday for a 3k mile trip, any suggestions for a fix?
