Ford Mustang Service Manual: Evaporator Core Housing
Heating and Defrosting
The heating and defrosting system has the following features:
- Controls the temperature and, during A/C operation, reduces the relative humidity of the air inside the vehicle.
- Delivers heated or cooled air to maintain the vehicle interior temperature and comfort level.
- Controls the A/C blower motor speed.
- Cooling or heating can be adjusted to maintain the desired temperature.
- System uses a reheat method to provide conditioned air to the passenger compartment.
- The blower motor (19805) draws outside air through the air inlet duct from just below the windshield during all system operations except for MAX A/C cooling (when recirculated air is used).
- All airflow from the blower motor passes through the A/C evaporator core (19860).
- The temperature is then regulated by reheating a portion of the air and blending it with the remaining cool air to the desired temperature.
- The temperature blending is varied by the air temperature control door, which regulates the amount of air that flows through and around the heater core (18476), where it is then mixed and distributed.
Heater Core
The heater core (18476) consists of fins and tubes arranged to extract heat from the engine coolant and transfer it to air passing through the heater core.
Blower Motor
The A/C blower motor (19805 ) pulls air from the air inlet and forces it into the plenum assembly where it is mixed and distributed.
Heater Hoses
NOTE: The heater water hoses connect to the heater core using quick disconnect couplers. The couplers are an integral part of the hose assemblies and cannot be separately serviced.
The heater water hoses (18472) provide a flexible connection between the engine and cooling system allowing hot water to travel from the engine to the heater core.

Analysis of Vibration
Inspection and Verification
Certain axle noise or vibration symptoms are also common to the engine,
transmission, wheel
bearings, tires, and other parts of the vehicle. For this reason, be sure that
the cause of the trouble is
