AIR INLET HOUSING
NOTE: The air inlet housing must be removed from HVAC housing and disassembled for service of the
recirculation-air door.

MOTOR-BLOWER
DESCRIPTION
The blower motor (1) is used to control the velocity of
air moving through the HVAC housing by spinning the
blower wheel (3) within the HVAC air inlet housing at
the selected speed.
The blower motor is a 12-volt, direct current (DC)
motormountedwithinaplastichousingwithaninte-
gral wire harness connector (2) and squirrel cage-type
blower wheel (3) that is secured to the blower motor
shaft (4). The blower wheel is positioned within the air
inlet housing on the passenger side end of the HVAC
housing.
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 ignition switch is in the Run position and the blower motor control is in
any position except Off. The blower motor receives battery current through the totally integrated power module
(TIPM) whenever the ignition switch is in the Run position.
Blower motor speed is controlled by regulating the ground path through or around the blower motor resistor and
through the blower motor control located within the A/C-heater control.
The blower motor can be accessed for service from underneath the instrument panel.
NOTE: The blower motor is supplied with a 12V feed from the TIPM, through theresistor block, whenever
the ignition switch is in the RUN position. Due to an open circuit conditionwithin the blower motor control
switch the TIPM is UNABLE to detect an OPEN circuit for the blower motor.
The blower motor control system is diagnosed using a scan tool (Refer to 24 -HVAC Electrical Diagnostics for more
information).
The blower motor and blower wheel are factory balanced and cannot be adjusted or repaired. If faulty or damaged,
the blower motor and wheel must be replaced as an assembly.
DIAGNOSIS AND TESTING
BLOWER MOTOR
WARNING: On vehicles equipped with airbags, disable the airbag system before attempting any steering
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: The blower motor is supplied with a 12V feed from the TIPM, through theresistor block, whenever
the ignition switch is in the RUN position. Due to an open circuit conditionwithin the blower motor control
switch the TIPM is UNABLE to detect an OPEN circuit for the blower motor.
To determine if an open condition exists within the blower motor circuit wiring, it is necessary to disconnect the
negative battery cable and check for continuity within the blower motor circuits using an ohmmeter. For circuit
descriptions and diagrams, refer to Air Conditioning/Heater in Group 8W -Wiring Diagrams.
OPERATION
Possible causes of the blower motor not operating include:
Faulty blower motor
Faulty blower motor circuit wiring or wire harness connectors
Faulty blower motor control
Possible causes of the blower motor not operating in one or more speeds include:
Faulty blower motor resistor
Faulty blower motor circuit wiring or wire harness connectors
Faulty blower motor control
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 connector 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
