The bugs after a vegatouch upgrade are out of control.
It is no longer a question of if something does not work after an upgrade but what does not work after an upgrade. Depending on your coach model, year, floor plan, etc….
If 12V reboot does not work. Try searching on this forum. I seem to remember something about the fans getting jacked up after an upgrade.
I love all the tech stuff but problems like yours can make us want manual switches on fans again.
