locate heat/ac re-circulation door actuator

Hi,

If you can't change the air flow direction, it sounds like a problem with what is called the mode door actuator. That is what changes the air flow direction.

What I would suggest is to remove the actuator and see if is responding when you change air flow direction. If it isn't, just confirm there is power to it when changes are made. If there is power, replace the actuator.

Here are the directions for replacement. The pic attached correlate with the directions.

MODE DOOR ACTUATOR REPLACEMENT
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.

See Pic 1

The mode door actuator is located on the lower left side of the HVAC unit housing.

REMOVAL
1. Open hood and disconnect the negative battery cable remote terminal from the remote battery post.
2. Remove left and right underpanel ducts.
3. Remove floor console.
4. Remove center floor heat adaptor duct.
5. Remove rear seat heat forward adaptor duct.
6. Loosen center support bracket and pry rearward to gain access to the actuator.
7. Remove actuator retaining screws. Then pull actuator straight down. Upon removal, note the shaft position of the actuator, because the shaft on this motor is keyed. When installing new actuator, its shaft must be positioned in the same location.
8. Remove electrical connection on actuator.

INSTALLATION
For installation, reverse the above procedures.
