The venting system on the AC ? heater has a mind of its own when I have the dial turned to have the air blow out the front of the dash board all it wants to do is blow out the defrost vents. I changed the check valve on the vacuum line coming off the engine but to no avail. Do you know whats wrong ? And is there any where on line where I can get a picture of a vacuum line diagram For the V-10

  1. The “MODE DOOR” is operated by an electronic actuator and will need to be checked and or replaced. The Control Head in the dash is what controls it. So if you find good signals coming from the control head and no motion from the actuator, replace the actuator.
