2018 Cascadia, the bunk fan stopped working. Weird thing is the bunk controls now control the vents up front. The EPU starts as normal, but nothing from the vent in the bunk. Just wanted to see if anyone ever had a similar issue.
Shut off the battery power for about 10 minutes, then bring it all back on line. There is a switch for that between the door and drivers seat. That will reset everything, and it might help.
