AIR FILTER
DESCRIPTION
A dust and odor air filter is standard equipment on
models equipped with the dual zone or three zone
temperature control systems (Fig. 1). The filter ele-
ment is the same size as the front air conditioner
evaporator to ensure ample filtering capacity. A
removable door on the bottom of the front heater-A/C
unit housing below the glove box provides easy access
to the filter element for replacement. Filter replace-
ment is recommended at 24,000 kilometer (15,000
mile) intervals.
REMOVAL
(1) Locate the air filter door on the bottom of the
lower evaporator housing just outboard of the pas-
senger side of the instrument panel center stack (Fig.
2).
(2) Slide the air filter door latch toward the rear of
the vehicle until it engages the opened stop on the
door.
(3) Pull the air filter door straight downward to
disengage it from the air filter opening of the lower
evaporator housing.
(4) Use your fingers to reach through the air filter
opening of the lower evaporator housing far enough
to grasp the air filter.
(5) Pull the air filter straight down and out of the
evaporator housing (Fig. 2).
INSTALLATION
(1) Note the ªAirflowº directional arrow imprinted
on the foam seal around the frame of the air filter.
This arrow should always be oriented towards the
center of the vehicle.
(2) With the air filter ªAirflowº arrow properly ori-
ented, carefully slide the filter fully upward into the
evaporator housing through the air filter opening.
(3) With the latch still positioned against its
opened stop, reinstall the air filter door onto the
lower evaporator housing air filter opening.
(4) Slide the air filter door latch toward the front
of the vehicle until it hits the closed stop on the door.
AIR OUTLETS
DESCRIPTION
Based upon the system mode selected, conditioned
air can exit the front heater-A/C unit housing
through one or a combination of the four main hous-
ing outlets: defrost, demist, panel, or floor. Once the
conditioned air exits the unit housing, it is directed
through molded plastic ducts to the various outlets in
the vehicle interior. These outlets and their locations
are as follows:
²Defroster Outlet- A single, centrally mounted
outlet delivers air for defrosting the large windshield.
Because outlet vanes are not needed to direct flow, a
simple, integral grid is molded into the center of the
instrument panel top cover to prevent objects from
falling into the duct. If the defroster outlet is faulty

or damaged, the instrument panel top cover must be
replaced.
²Demister Outlets- There are two side window
demisters that aid in defogging and defrosting the
front door windows. One demister outlet is located at
each outboard end of the instrument panel top pad,
near the belt line at the A-pillars. The demister out-
lets can be removed from the top pad individually for
service replacement.
²Instrument Panel Outlets- There are five
panel outlets in the instrument panel, one located
near each outboard end of the instrument panel fac-
ing the rear of the vehicle, and three located near the
top of the instrument panel center bezel. On models
with manual temperature control, all five of these
outlets are fully adjustable. On models with Auto-
matic Temperature Control (ATC), the center outlet
in the center bezel has fixed vanes because it also
houses the remote infrared temperature sensors for
the front seat positions. The outboard outlets can be
removed individually for service replacement. The
center bezel outlets are serviced as a gang of three
outlets and, on models with ATC, also includes the
infrared sensors.
²Front Door Rear Outlets- A fully adjustable
outlet located at the rear of each front door trim
panel supplies only cooled air to the intermediate
seat passengers. Air is supplied to these outlets from
the instrument panel through ducts in the doors that
use molded seals at the instrument panel to prevent
air leakage. The door ducts are integral to the front
door trim panels. These outlets also incorporate a red
reflector to improve the safety and visibility of an
opened front door to traffic approaching the vehicle
from the rear at night. These outlets can be removed
from the door trim panels for service replacement.
²Front Floor Outlets- There are two front floor
outlets, one located above each side of the floor panel
center tunnel below the instrument panel. These out-
lets are integral to the front heater-A/C unit distri-
bution housing.
²Rear Floor Outlets- Wide rear floor outlets
located under each front seat have integral, fixed
directional dividers to distribute heated air across
the floor for intermediate seat passengers. These out-
lets are integral to the floor distribution ducts routed
under the front floor carpet from an outlet nozzle on
the bottom of the front heater-A/C unit distribution
housing.

REMOVAL - CENTER BEZEL OUTLETS
The three outlets located near the top of the
instrument panel center bezel are serviced only as a
set of all three outlets. If the vehicle is equipped withthe optional Automatic Temperature Control (ATC)
system, the center outlet of the three has fixed vanes
and also houses the remote front infrared tempera-
ture sensors.

BLOWER MOTOR
DESCRIPTION
The blower motor is a 12-volt, Direct Current (DC)
motor with a squirrel cage-type blower wheel that is
secured to the blower motor shaft (Fig. 7). The
blower motor and wheel are located near the passen-
ger side end of the heater-A/C unit within the two
halves of the intake air housing in the passenger
compartment below the instrument panel. The
blower motor and blower motor wheel are a factory
balanced unit and cannot be adjusted or repaired. If
faulty or damaged, the blower motor and blower
wheel must be replaced as a unit.
OPERATION
The blower motor will operate whenever the igni-
tion switch is in the On position and the heater-A/C
control power is turned on. The blower motor can
only be turned off by turning off the power at the
heater-A/C control. The blower motor receives battery
current whenever the front blower motor relay is
energized. The front blower motor relay output cir-
cuit is protected by a fuse in the Intelligent Power
Module (IPM) located in the engine compartment
near the battery. In the Manual system, the blower
motor speed is controlled by regulating the path to
ground through the blower control switch and the
blower motor resistor. In the ATC system, the blower
motor speed is controlled by an electronic blower
power module, which uses a pulse width modulated
input from the ATC module and feedback from the
blower motor to regulate the blower motor ground

path it provides. The blower motor and wheel are
used to control the velocity of air moving through the
heater-A/C unit housing. The blower motor controls
the velocity of the air flowing through the heater-A/C
housing by spinning the blower wheel within the
housing at the selected speed or, in the ATC system,
at the selected or programmed speed.
