Thanks for visiting Just Answer,
Let's try resetting it.

1. Recalibrate the temperature actuators.

2. Make sure both the driver's and passenger side actuators are near the middle position.

3. Remove the HVAC/ECAS fuse for a minimum of 10 seconds.

4. Install the HVAC/ECAS fuse.

5. Start the vehicle and wait 40 seconds for the HVAC control module to self-calibrate.

6. Verify that no DTCs have set as current DTCs.
