Heating & Air Conditioning (Service Information): Description

A single zone Heating, Ventilation and Air Conditioning (HVAC) system or a manually controlled heater-only system are available equipment on this vehicle, depending on market.

To maintain the performance level of the 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 the appropriate cooling service information for more information before opening or attempting any service to the engine cooling system.

All vehicles are equipped with a common HVAC housing (1). The HVAC 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:

1. Cabin filter
2. Mode door
3. Air inlet housing
4. Front floor ducts
5. Mode door actuator
6. Recirculation door actuator
7. Blower motor
8. Blower motor power module
9. Heater core
10. Blend door actuator
11. A/C evaporator (A/C system only)

On heater-only systems, the A/C evaporator is omitted from the HVAC housing and is replaced with an air restrictor plate.

Based upon the system mode selected, conditioned air can exit the standard heater-only or optional 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 HVAC air distribution housing and the floor outlets are located on each side of the distribution housing. Once the conditioned air exits the HVAC housing, it is 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, near the base of the windshield.
• Side Window Demister Outlets  - There are two side window demister outlets, one is located at each outboard end of the instrument panel top cover, near the belt line at the A-pillars.
• 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 on each side the floor panel center tunnel behind the instrument panel.
