QuestionQUESTION: Hi my 99 Concorde does not seem to want to go to defrost setting on panel switch. Floor and recycle seem to be okay. I have recently replaced the blower capacitor. I am wandering if I should check for a vacuum conection or if there is some sort of deflector assembly that should be lubed? Thank You
ANSWER: there is no vac any more it all done with motors.

QUESTION: Sorry I live in Canada too far away for either of us. I do know it works with motors as I have had it apart. Everything seems to be turning as I can feel and see it working. I think something must be blocking the door. How do you get at the door assembly on this thin?
Thanks for your reply!
Answerpossible broken door here is the stuff to the motor.
MODE DOOR ACTUATOR
The mode door actuator is an electric motor. It mechanically positions the A/C unit panel/bi-level door and the floor/defrost door. This actuator contains a feedback strip which allows the computer control to know the exact position of the mode door at all times. The mode door actuator is not serviceable and must be replaced if found to be defective.
The mode door actuator is located on the lower left side of the HVAC unit housing Mode Door Actuator Location
