Park Avenue V6-3.8L VIN K (1995)
Blower Motor: Description and Operation
A/C Purge Mode
DESCRIPTION
Moisture tends to accumulate in the heater and A/C module assembly after the engine has been shut off. When the engine is re-started and the A/C
system turns on, this moisture may be expelled from the instrument panel outlets toward front seat occupants.
OPERATION
On start-up, the programmer checks for indications that this may occur. If so, the programmer energizes the heater solenoid to direct air toward the
floor, and runs the blower at 80% of maximum speed for four seconds. The programmer then resumes normal system operation.
A/C PURGE mode is bypassed if the fan is operating in manual mode or if DEFROST mode is chosen at start-up.
