A/C Purge Mode

Moisture tends to accumulate in the ECC module assembly after the engine has been turned off. When the engine is restarted and the A/C system turns ON, this moisture may be expelled from the panel outlets toward the front seat occupants.

During startup, the heater and ECC module inspects for indications that this condition may occur. If this condition occurs, the ECC module performs the following actions:
^ Positions the A/C door in order to direct air toward the floor
^ Operates the blower

The ECC module then resumes normal system operation.
