BLOWER MOTOR

DESCRIPTION

The blower motor is a 12-volt, direct current (DC)

motor mounted within a plastic housing with a squir-
rel cage-type blower wheel that is secured to the
blower motor shaft and an integral wire harness with
a grommet and connector (Fig. 6). The blower motor
and wheel is located in the air inlet housing at the
passenger side end of the HVAC housing.

The blower motor can be accessed for service from

underneath the instrument panel.

OPERATION

The front blower motor is used to control the veloc-

ity of air moving through the front HVAC housing by
spinning the blower wheel within the housing at the
selected or programed speed (depending on applica-
tion).

On models equipped with the manual temperature

control (MTC) heating-A/C system, the front blower
motor will operate whenever the ignition switch is in
the On position and the blower control switch is in
any position except Off. On models equipped with the
automatic temperature control (ATC) heating-A/C
system, the front blower motor will operate whenever

the ignition switch is in the On position and the A/C-
heater control power is turned on.

The front blower motor relay output circuit is pro-

tected by a fuse in the integrated power module
(IPM) located in the engine compartment. In the
MTC system, the front blower motor speed is con-
trolled by regulating the path to ground through the
blower control switch and the blower motor resistor.
In the ATC system, the front blower motor speed is
controlled by an electronic blower motor power mod-
ule, which uses a pulse width modulated input from
the A/C-heater control and a feedback signal from the
blower motor to regulate the blower motor ground
path. On both systems, the front blower motor
receives battery current whenever the front blower
motor relay is energized.

The front blower motor and blower motor wheel

are factory balanced and cannot be adjusted or
repaired. If faulty or damaged, the front 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 battery negative (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.

For circuit descriptions and diagrams, refer to Air

Conditioning/Heater in Group 8W - Wiring Diagrams.
Possible causes of an inoperative front or rear blower
motor include:

• Faulty fuse (the fuse is located in the integrated

power module (IPM) in the engine compartment)

• Faulty blower motor circuit wiring or wire har-

ness connectors

• Faulty blower motor resistor or power module

(depending on application)

• Faulty blower motor relay

• Faulty blower motor switch

• Faulty blower motor.

VIBRATION

Possible causes of front or rear blower motor vibra-

tion include:

• Improper blower motor mounting

• Improper blower wheel mounting

• Blower wheel out of balance or deformed

• Foreign material in blower wheel causing out of

balance condition

• Blower motor faulty.

NOISE

To determine if the front or rear blower motor is

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

• Foreign material in the HVAC housing

• Improper blower motor mounting

• Improper blower wheel mounting

• Blower motor faulty.
