AC Dash Fan not working on Vegas 24.1

Ive had a intermittent blower fan on the dashboard AC on my Vegas for over a year. Several times it just simply stopped working. Jiggling the wiring under the dash would eventually fix it. Finally traced it down to the connector to the blower fan under the dash in the cab on the passenger side.

Its was 2 conductor red/black connector right at the fan. Disconnected it and found some excess rubber from the connectors insulation had gotten lodged inside the contact area. Cleaned it out with a small drill bit and now it works perfectly.

I highly suggest contacting Thor and have them email you the manual for the AC unit in your coach. All Class A units do not have factory air. The system is an aftermarket unit made by Evans. Ford wont touch it, most RV places don't have a AC tech much less a manual. Having the manual can really be valuable to troubleshoot and allowing someone to maintain the unit.

As an aside if you ever try to find the Low pressure fitting to add refrigerant it is way up under the dash, in the engine compartment, in the bend of the line just before it enters the evaporator coil. You have to be a contortionist with a 4 foot arm to get to it

Hope this helps someone someday! Better yet I hope you never need the help

2017 Vegas 24.1
