Cadillac Seville STS Improper HVAC Temperature and/or Air Delivery Due to Failed Mode Door Actuator

(HVAC) temperature and/or air delivery on passenger side blows out cold air all the time. Even if you shut odd passenger heat or AC control.
The only way it is stopped is to shut off the main Climate control switch on the drivers side
