QuestionPROABLEM: Passenger side only emits heated air.
MY SKILL LEVEL: I am not a mechanic or electrician, however I can read a analog volt meter and I know which way to turn a wrench.
VERIFIED CONDITIONS:
1- Passenger temperature control (Located on passenger door.) illuminates when pushed to turn on, however turning the control knob to adjust temperature has no effect on passenger air.
2- The main Climate Control Center functions as designed, heating and cooling the driver side as desired. Blower Speed Control functions as designed for both driver and passenger sides.
3- Air door motor (Located behind Glove Box.) does not respond to controls. Air door moves freely when control arm is disconnected from motor. All electrical and pneumatic wires and hoses are properly connected.
Your help will be greatly appreciated.

AnswerEither the switch is faulty and or the passengers side ACTUATOR that controls the air mix door is inoperative of which you most likely already suspected.
You will need several pictures and directives to test these 2 items and as far as I know, this website only allows ONE hand drawn picture.
