HVAC Control Module Replacement

If the HVAC manual or HVAC automatic control modules are replaced, an automatic re-calibration of all the actuators will occur. Be sure to check Service Programming System (SPS)  for the latest calibration software. For the best re-calibration results, start and run the engine for at least one minute after installing the new module. Do not adjust any controls on the HVAC control module during the re-calibration procedure. If interrupted, improper HVAC performance may result. No additional procedures are necessary.
