    I have a 2019 5700xe without ATC. 12v at fuse, 2v at HVAC controller. Any ideas where to look or does a sensor have a reputation for this? Sleeper controller won’t power up either.

    Sounds like you need to check wiring. Post the unit's last 6 of vin, and I can show some wiring of what to check if you'd like.

    It was the plug that plugs into the back of the fuse block. Terrible design.

    Thanks! So you only had 2 volts at the cab Module? My fan is the only thing that works, nothing else, bunk won't work either

    Yes at the control panel, but fan didn't work.
