Ford Mustang Service Manual: Register - LH

Air Distribution

NOTE: The air distribution system of this vehicle cannot be equipped with a cabin air filter.

There are two sources of air available to the air distribution system:

  • outside air
  • recirculated air

Recirculated air is only used during MAX A/C.

Air distribution within the vehicle is determined by the function selector switch position. Airflow control doors are used to direct airflow within the air plenum chamber. Vacuum control motors (18A318) are used to position these airflow control doors. Refer to Section for a description and operation of each of the system functions.

The air distribution system is designed to provide airflow from the defrost nozzle when no vacuum is applied to any of the vacuum control motors. This is done to prevent a situation where defrost cannot be obtained due to a system vacuum leak.

Air enters the passenger compartment from the:

  • instrument panel A/C register (19893).
  • heater outlet floor duct (18C433).
  • windshield defroster hose nozzle (18490).
  • side window demisters.

Passenger compartment air is exhausted from the vehicle through open windows or body air vents.

Instrument Panel Registers

There are A/C registers on the left and right sides of the instrument panel and in the center instrument panel finish panel.

The LH and RH A/C registers are only serviceable as assemblies.

The center A/C registers are not serviceable as assemblies. The registers are installed with the instrument panel center finish panel assembly.
