Heating and Air Conditioning - Description

DESCRIPTION

A manual temperature control (MTC) single zone type heating-A/C system is standard on this model.

To maintain the performance level of the heating, ventilation and air conditioning (HVAC) system, the engine cooling system must be properly maintained. The use of a bug screen is not recommended. Any obstructions in front of the radiator or A/C condenser will reduce the performance of the A/C and engine cooling systems.

The engine cooling system includes the radiator, thermostat, radiator hoses and the engine coolant pump. Refer to Cooling System for more information before opening or attempting any service to the engine cooling system.





The heating-A/C system combines A/C, heating, and ventilating capabilities in a single HVAC housing mounted within the passenger compartment beneath the instrument panel. The HVAC housing includes:

- Recirculation door actuator (1)
- Recirculation-air door (2)
- A/C evaporator (3)
- Wire harness connector (4)
- Blend door actuator (5)
- Wire harness connector (6)
- Floor/defrost mode door actuator (7)
- Panel mode door actuator (8)
- Wire harness connector (9)
- Mounting bracket (10)
- Evaporator drain tube (11)
- Heater core (12)
- Blower motor (13)
- Blower motor resistor (14)
- Mounting bracket (15)
- Mounting bracket (16)

Based upon the system and mode selected, conditioned air can exit the HVAC housing through one or a combination of the three main housing outlets: defrost, panel or floor. The defrost and panel outlets are located on the top of the housing and the floor outlet is located on the bottom of the housing. Once the conditioned air exits the HVAC housing, it is further directed through molded plastic ducts to the various outlets within the vehicle interior. These outlets and their locations are as follows:

- Defroster Outlet - A single large defroster outlet is located in the center of the instrument panel top cover, near the base of the windshield.
- Panel Outlets - There are four panel outlets in the instrument panel, one located near each outboard end of the instrument panel facing the rear of the vehicle and two located near the top of the instrument panel center bezel.
- Front Floor Outlets - There are two front floor outlets, one located above each side of the center of the floor panel near the dash panel.
