DTC P066A Ford

Description

The HVAC Module monitors the total door movement range. If the door movement is less then or greater than what the controller has stored in its memory, or if the door movement is stalled or stuck, this DTC will set. If the HVAC Module detects a valid door movement span in both directions, the DTC will change from Active to Stored and will stay in the controllers memory for 100 ignition cycles.
