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.

I'm having the same issue here in a 2019 5700xe! What was the problem?
