system air filter. The filter is mounted under the
hood in the outside-air intake of the HVAC housing.
The filter should be checked and replaced at least
once every 24,000 km (15,000 miles) and checked if
A/C-heater system performance seems lower than
expected.

REMOVAL

(1) Remove the passenger side cowl grille screen

(Refer to 23 - BODY/EXTERIOR/COWL GRILLE
SCREEN - REMOVAL).

(2) Loosen the bolts that secure the windshield

washer reservoir to the body.

NOTE: Removal of the reservoir is not necessary.
Loosen reservoir just enough to allow access to the
filter element.

(3) Remove the filter element by lifting the filter

element up and out of the housing.

INSTALLATION

(1) Install filter element by inserting the element

down directly into the element housing. The filter is
held in place by friction between the filter element
and the housing so no fasteners are used.

(2) Position

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. 3). The
blower motor and wheel are located near the passen-
ger side end of the HVAC 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 (Refer to 24 -
HEATING & AIR CONDITIONING/DISTRIBUTION/
BLOWER MOTOR - REMOVAL).

OPERATION

The blower motor will operate whenever the igni-

tion switch is in the On position, and the blower con-
trol switch is in any position except Off. The blower
motor circuit is protected by a fuse in the instrument
panel fuse block. The blower motor speed is con-
trolled by regulating the battery feed through the
blower control switch and the blower motor resistor.

The blower motor and wheel are used to control the
velocity of air moving through the heater-only or A/C-
heater systems. The blower motor controls the veloc-
ity of the air flowing through the HVAC housing by
spinning the blower wheel within the housing at the
selected speed.

DIAGNOSIS AND TESTING

BLOWER MOTOR

WARNING: On vehicles equipped with airbags, dis-
able the airbag system before attempting any steer-
ing wheel, steering column, or instrument panel
component diagnosis or service. Disconnect and
isolate the negative battery (ground) cable, then
wait two minutes for the airbag system capacitor to
discharge before performing further diagnosis or
service. Failure to take the proper precautions
could result in accidental airbag deployment and
possible personal injury or death.

NOTE: For circuit descriptions and diagrams, refer
to Air Conditioning/Heater in Group 8W - Wiring
Diagrams.

OPERATION

Possible causes of an inoperative blower motor or

blower motor not operating in all speeds include:

• Faulty fuse

• Faulty blower motor resistor

• Faulty blower motor switch

• Faulty blower motor

DISTRIBUTION

AIR OUTLETS (Continued)

• Faulty blower motor circuit wiring or wire har-

ness connectors

VIBRATION

Possible causes of blower motor vibration include:
• Improper blower motor mounting

• Improper blower wheel mounting

• Deformed blower wheel

• Out of balance blower wheel due to foreign

material in the wheel

• Faulty blower motor

NOISE

To determine if the blower motor is the source of

the noise, simply switch the blower motor from Off to
On. To verify that the blower motor is the source of
the noise, unplug the blower motor wire harness con-
nector and operate the heating-A/C system. If the
noise goes away, possible causes include:

• Foreign material in the HVAC air inlet housing

• Improper blower motor mounting

• Improper blower wheel mounting

• Faulty blower motor

REMOVAL

NOTE: The blower motor is located on the bottom
right side of the HVAC housing. The blower motor
can be removed from the vehicle without having to
remove the HVAC housing.
