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.
The air outlets cannot be serviced separately.

Each of the instrument panel air outlets contain an

air outlet barrel that is used to direct or shut off the
flow of the conditioned air leaving the instrument
panel.

All of the instrument panel air outlets barrels can

be serviced individually.

REMOVAL

NOTE: The instrument panel air outlet barrels are
retained into the air outlets by a light snap fit.

(1) Using a trim stick C-4755 or equivalent, gently

pry on the instrument panel air outlet barrel(s) until
the barrel retainers release from the pivot shafts of
the air outlets (Fig. 1).

(2) Remove the barrel(s) from the air outlet(s). If

needed, use a trim stick to help remove the barrels.

INSTALLATION

(1) Position the air outlet barrel(s) into the air out-

let(s).

(2) Gently push the barrel(s) into the air outlet(s)

until it snaps into position on the outlet pivot shafts.

DISTRIBUTION

BLOWER MOTOR

DESCRIPTION

The blower motor (Fig. 2) is a 12-volt, direct cur-

rent (DC) motor mounted within a plastic housing
with an integral wire connector and squirrel cage-
type blower wheel that is secured to the blower
motor shaft. The blower motor wheel is located in the
HVAC air inlet housing which is mounted to the pas-
senger side end of the HVAC housing.

The blower motor can be accessed for service from

underneath the instrument panel.

OPERATION

The blower motor is used to control the velocity of

air moving through the HVAC housing by spinning
the blower wheel within the HVAC air inlet housing
at the selected speed.

The blower motor will operate whenever the igni-

tion switch is in the On position and the blower
motor control in any position except Off. Blower
motor speed is controlled by regulating the path to
ground through the blower motor resistor and
through the blower motor control located within the
A/C-heater control.

The blower motor and blower motor wheel are fac-

tory balanced and cannot be adjusted or repaired. If
faulty or damaged, the blower motor and blower
wheel must be replaced as an assembly.

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

• Faulty blower motor circuit wiring or wire har-

ness connectors

Possible causes of the

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

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 battery negative (ground) cable, then
wait two minutes for the airbag system capacitor to
discharge before performing further diagnosis or
service. This is the only sure way to disable the air-
bag system. Failure to take the proper precautions
could result in an accidental airbag deployment and
possible personal injury or death.

NOTE: The blower motor is located on the passen-
ger side of the vehicle under the instrument panel.
The blower motor can be removed without having
to remove the instrument panel or the HVAC hous-
ing.

(1) Disconnect and isolate the negative battery

cable.

(2) Disconnect the wire harness connector from the

blower motor (Fig. 3).

(3) Disconnect the air intake duct from the blower

motor.

(4) Remove the screws that secure the blower

motor to the bottom of the HVAC housing.

(5) Rotate and tilt the blower motor as needed for

clearance to remove the blower motor and wheel
from the HVAC housing.

INSTALLATION

(1) Align and install the blower motor into the

HVAC housing.

(2) Install the screws that secure the blower motor

to the HVAC housing. Tighten the screws to 2 N·m
(17 in. lbs.).

(3) Connect the air intake duct to the blower

motor.

(4) Connect the wire harness connector to the

blower motor.

(5) Reconnect the negative battery cable.

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

discharge before performing further diagnosis or
service. This is the only sure way to disable the air-

could result in an accidental airbag deployment and
possible personal injury or death.

NOTE: The defroster duct assembly consists of two
seperate

ducts.

The

attached to the instrument panel top pad and the
lower defroster duct is attached to the HVAC hous-
ing behind the instrument panel.
