Chassis A/C Stopped Working

Just took our 2016 Vegas out to fill the gas tank and for it's monthly exercise.

We are leaving for the Cape in 2 weeks so I figured to get going on my check list.

After I restarted returning home the rig to put it back in it's house and the chassis a/c stopped working. Not blowing hot air but not working at all as in no fan or activity of any kind and the indicator light on the push button switch on the dash is out as well.

This acts like a "no power" situation and as such I will start checking fuses first.

Anybody had any similar experiences ?

Captmetal, I found the link.
I have no power at the fan switch so i will have to locate the fuse that controls the HVAC and check my connections.

Hiya petew, the same here. No dash AC, no blower motor switch, no recirculator switch, no cameras, and the radio is whacked! (unable to turn off or change mode, it only scrolls nonsense trash like the Matrix) We test drove an Axis that had no dash AC and bought the one that did only to have it fail as we headed out for 10 days. We went immediately to the dealer, 2 techs for 3 hours, all fuses, under dash and under hood were okay. They say it's from the Ford side but I'm feeling Thored. During this 10 day trip, the AC and controls would work for an hour +/- until some circuit board warms up and then it's conked out again the rest of the day.
Contrary to dealer myth, driving with the genny and roof AC does NOT cool the cab. Just got back and it goes in tomorrow until r&r'd.

Well I fixed it.. With no help from my Thor paperwork.
What I found is that the HVAC fuses on my 24.1 are located in the fuse box which is in the external storage bin directly behind the driver side front wheel.

The bottom fuse in that fuse box is a 25amp unit that controls the HVAC fan , the fuse above that is HVAC related also.
The 25 amp fuse was blown and once replaced I had a/c.

This storage bin also contains what I believe to be the slide controller for the bunk located over the drivers area.

I am glad that this happened while I was at home and not on the road. The fix was simple enough it was just a matter of locating the problem.

No that is the slide controller for the slide.

The controller for the bunk is hidden in the cabinet above the sink.
