automatic temperature control (ATC) heating-A/C
system, use a 12-volt, direct current (DC) rear blower
motor. The rear blower motor has an integral wire
harness and two squirrel cage-type blower wheels
that are secured to the blower motor shaft (Fig. 1).
The blower motor and wheels are contained within
the two halves of the rear blower motor housing,
which is located under the front center floor console
cover.

OPERATION

The rear blower motor and wheels are used to con-

trol the velocity of air moving through the center
floor console ducts by spinning the blower wheels
within the housing at the selected or programmed
speed (depending on application).

The rear blower motor will operate whenever the

ignition switch is in the On position and the power
for the A/C-heater control of the automatic tempera-
ture control (ATC) heating-A/C system is turned on.
When the ATC A/C-heater control display reads
REAR AUTO or when the rear blower motor is off,
the switch located in the center console between the
second row seats is not functional. When the A/C-
heater control display reads REAR, only the rear
seat occupants control the rear blower motor speed
from the rear switch. When in the Rear mode, the
rear occupants can set the rear switch to any blower
motor speed including OFF or AUTO. While in the
Auto position, the rear blower motor speed will be
automatically controlled.

The rear blower motor speed is controlled by an

electronic blower motor power module, which uses a
pulse width modulated input from the ATC A/C-
heater control and feedback signal from the rear
blower motor to regulate the blower motor ground
path. The rear blower motor receives battery current
whenever the rear blower motor relay is energized.

For diagnosis and testing of the rear blower motor,

refer to 24 - HEATING & AIR CONDITIONING/DIS-
TRIBUTION - FRONT/BLOWER MOTOR - DIAG-
NOSIS AND TESTING.

The rear blower motor and blower motor wheels

are factory balanced and cannot be adjusted or
repaired. If faulty or damaged, the rear blower motor
and blower wheels must be replaced as an assembly.

REMOVAL

NOTE: The rear blower motor and blower wheels
are serviced only as a balanced unit. If either com-
ponent is faulty or damaged, the entire blower
motor and wheel assembly must be replaced.

(1) Remove the front center floor console cover

(Refer to 23 - BODY/INTERIOR/CENTER CONSOLE
- REMOVAL).

(2) Disconnect and isolate the negative battery

cable.

from the rear blower motor power module and the
rear mode door actuator (Fig. 2).

(4) Remove the body wire harness bracket from

the console support bracket.

(5) Remove the eight screws and the two console

support brackets from the floor console base and duct
assembly

(6) Remove the four screws that secure the rear

blower motor housing to the floor console base and
duct assembly.

(7) Remove the rear blower motor housing and

place it on a bench.

(8) Disconnect the rear blower motor wire harness

connector from the power module.

(9) Remove the eleven retaining clips and three

screws that secure the housing together.

ing.

(11) Remove the blower motor wire harness and

grommet from the housing and remove the blower
motor (Fig. 3).

INSTALLATION

(1) Position the rear blower motor into the housing

and install the blower motor wire harness and grom-
met.

(2) Assemble the two halves of the rear blower

motor housing and install the eleven retaining clips
and three screws. Tighten the screws to 2 N·m (17 in.
lbs.).

(3) Connect the rear blower motor wire harness

connector to the rear blower motor power module.

(4) Position the rear blower motor housing into the

floor console.

(5) Install the four screws that secure the rear

blower motor housing to the floor console base.
Tighten the screws to 2 N·m (17 in. lbs.).

(6) Position the two console support brackets onto

the floor console base.

(7) Install the eight screws that secure the support

brackets to the floor console base. Tighten the screws
to 2 N·m (17 in. lbs.).

(8) Install the body wire harness bracket onto the

console rear support bracket.

(9) Connect the body wire harness connectors to

the rear blower motor power module and the rear
mode door actuator.

(10) Reconnect the negative battery cable.
