Air conditioner front vents do not blow heat or anything?

Hi,

Does the blower motor work at any speed? Can you hear it run? Can you get air flow from under the dash or defroster?

Let me know because there are different actuators. For example, the air temperature entering the vehicle is controlled by a blend air door actuator. The airflow direction is controlled by a mode door actuator. There are others as well.

Let me know.

Take care,

Joe

This sounds like a mode actuator which controls the vent operation, here is the location so you can check it out.

Actuator Recalibration (Primary)

When replacing the HVAC control module, it will be necessary to allow the HVAC control module to perform a calibration process. When installing the HVAC control module be sure to perform the following:

Important: Do not adjust any controls on the HVAC control module while the HVAC control module is self-calibrating. If interrupted, improper HVAC performance will result.

1. Place the ignition switch to the Off position.
2. Disconnect the scan tool.
3. Install the HVAC control module.
4. Connect all previously disconnected components.
5. Start the vehicle.
6. Wait 40 seconds for the HVAC control module to self-calibrate.
7. Verify that no DTCs have set as current DTCs.
