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.
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
