I drive the car listed above Limited. My battery drained and after I jumped it, my A/C will only blow in the floorboard. How do I recalibrate the mode actuator without a scan tool?

Sure, here is how to recalibrate the blend door actuator:

Alternate Method (without Scan Tool)

Note: Do not operate any HVAC controls while the HVAC control module is calibrating as this may interrupt the process. If interrupted, improper HVAC performance will result.
Ignition Off - Vehicle Off.

Remove the HVAC control module fuse for a minimum of 20 seconds. Install the HVAC control module fuse. Start the vehicle. Wait 1 minute for the HVAC control module to self - calibrate.


Please let us know if you need anything else to get the problem fixed.
