A/C Purge

In A/C PURGE, the blower operates at a medium speed for 4 seconds with the air primarily directed out of the heater outlets.

During the A/C PURGE, the hot, moist air is purged from the A/C module and the floor ducts. The evaporator begins to cool the incoming air. The heater and A/C programmer automatically resumes normal air mode delivery control once the A/C PURGE is completed.
