Actuators Recalibration

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.

Use the following steps to perform the calibration update:

  1. Ignition in ON position or engine running.
  2. Simultaneously press the A/C and recirculation buttons on control head 3 times in less than 2 seconds.
  3. The Mode setting lights will flash during calibration and will quit flashing once calibration is completed.
  4. This calibration process can take up to 30 seconds.
