Park Avenue V6-3.8L VIN K (1995)
Blower Motor: Description and Operation
Cold Purge Mode
DESCRIPTION
In cold weather, moist breath air from vehicle occupants may condense on the windshield.
OPERATION
On cold engine start-up, the programmer checks for indications that this may occur. If so, the programmer energizes the A/C solenoid to direct air out
the windshield outlets and runs the blower at 60% of maximum speed for twenty seconds. The programmer then resumes normal system operation.
COLD PURGE mode is bypassed if the fan is operating in manual mode or if DEFROST mode is chosen at start-up.
