DESCRIPTION
ENGINE COOLING SYSTEM
To maintain the performance level of the heating-
A/C system, the engine cooling system must be in
proper working order. The use of a bug screen is not
recommended. Any obstructions in front of the radia-
tor 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 for more information before
opening or attempting any service to the engine cool-
ing system.
HEATER AND AIR CONDITIONER SYSTEM
A manually controlled single zone type heating-air
conditioning system or a manually controlled heater-
only system is available as standard equipment on
this model (depending on market).
All vehicles are equipped with a common heater,
ventilation and air conditioning (HVAC) housing (Fig.
1). The system combines air conditioning, heating
and ventilation capabilities in a single unit mounted
within the passenger compartment under the instru-
ment panel. The HVAC housing includes:
• Blower motor
• Blower motor resistor
• Recirculation-air door and actuator (A/C system
only)
• Heater core
• A/C evaporator (A/C system only)
• Mode-air door
On heater-only systems, the evaporator coil is
omitted from the 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
heater-A/C unit housing through one or a combina-
tion of the three main housing outlets: defrost, panel
or floor. The defrost outlet is located on the top of the
housing, the panel outlet is located on the face 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 fol-
lows:
• Defroster Outlet - A single large defroster out-
let 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
