2014 Thor Miramar 34.2 cab A/C not working

[Swampi28]

I have a 2014 Thor Miramar 34.2 motorhome and the cab a/c does not work when on Max A/C. I have had this problem for years but have never gotten it checked out. I did use this motorhome a lot (only has 15,000 miles on it). Now that I have time to use it, my wife and I will be traveling and want to make sure its good to go. Any suggestions? I already replaced it with new tires and new furnace blades. So I'm slowly getting back to travel condition.

Define "Max A/C". Does the A/C work when not on "Max A/C"?
Have you had an auto A/C shop look at it? There's really nothing special or unique about an RV dash A/C from any other auto style A/C.

And what's a "furnace blade"?

I belive that model has a master breaker tucked in behind the battery box. It is completely separate from either of your other two breaker panels. It is likely that when doing the repair or when the old battery failed it tripped that breaker.
