    This step should be done before trying to fix HVAC errors. It is the only true way to know if any current existing errors.

    In fault code mode (http://import-era.com/threads/w210-hvac-diagnosis.1206/) press both AUTO switches simultaneously for more than 5 seconds (after last trouble code is displayed).

    Once codes are cleared you will see display change to "d and FF" switch ignition off and all codes are erased.
