Description

HEATER AND AIR CONDITIONER

A manually controlled single zone type heating-air conditioning system, manually controlled dual zone type heating-air conditioning system, manually controlled three zone type heating-air conditioning system or an automatic controlled three zone type heating-air conditioning system is available 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.

All vehicles are equipped with a common heater, ventilation and air conditioning (HVAC) housing (Figure 1). The system combines air conditioning, heating, and ventilating capabilities in a single unit housing mounted within the passenger compartment under the instrument panel.






Figure 1 RS/RG HVAC Housing






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 unit housing, it is further directed through molded plastic ducts to the various outlets in 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.
- Side Window Demister Outlets - There are two side window demister outlets, one is located at each outboard end of the instrument panel, near the A-pillars.
- Panel Outlets - There are five panel outlets in the instrument panel, one located near each outboard end of the instrument panel facing the rear of the vehicle and three 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.
