(1) Disconnect and isolate the battery negative
cable.
(2) Unplug the vacuum harness connector from the
recirculation door actuator (Fig. 19).(3) Insert a trim stick or another suitable wide
flat-bladed tool into the latch hole on the HVAC
housing actuator mount (Fig. 20).
(4) Gently pry the actuator latch while pulling
firmly outwards on the actuator to remove the actua-
tor from the mount (Fig. 21).
(5) Disengage the hole on the end of the actuator
link from the hooked pin on the end of the recircula-
tion door lever.
(6) Remove the recirculation door vacuum actuator
from the vehicle.
INSTALLATION
(1) Install the recirculation door vacuum actuator
by slipping the arm on to the hole on the end of the
actuator link with the hooked pin on the end of the
panel/demist door lever.
(2) Snap the actuator back into its mount.
(3) Plug in the vacuum harness connector to the
recirculation door actuator.
(4) Connect the battery negative cable.

AIR OUTLETS
DESCRIPTION - DEMISTER OUTLETS
The side window demister outlets are integral to
the instrument panel end caps(Refer to 23 - BODY/
INSTRUMENT PANEL/INSTRUMENT PANEL END
CAP - REMOVAL) and (Refer to 23 - BODY/INSTRU-
MENT PANEL/INSTRUMENT PANEL END CAP -
REMOVAL).
REMOVAL - PANEL OUTLET BARRELS
(1) Use a trim stick or another suitable wide flat-
bladed tool to gently pry the panel outlet barrels out
of the panel outlet housing (Fig. 1). The barrel is
retained by a light snap fit.
INSTALLATION - PANEL OUTLET BARRELS
To install, position the barrel in the panel outlet
housing and press firmly until the barrel snaps into
place.

BLOWER MOTOR
DESCRIPTION
The blower motor and blower wheel are located in
the passenger side end of the HVAC housing, below
the glove box. The blower motor controls the velocity
of air flowing through the HVAC housing by spinning
a squirrel cage-type blower wheel within the housing
at the selected speed. The blower motor and wheel
can be removed from the housing inside the vehicle
without removing the dash or HVAC housing assem-
bly.
OPERATION
The blower motor will only operate when the igni-
tion switch is in the On position, and the A/C Heater
mode control switch knob is in any position, except
Off. The blower motor receives a fused battery feed
through the blower motor relay whenever the igni-
tion switch is in the On position. The blower motor
battery feed circuit is protected by a fuse in the
Power Distribution Center (PDC). Blower motor
speed is controlled by regulating the ground path
through the A/C Heater control blower motor switch
and the blower motor resistor.
The blower motor and blower motor wheel cannot
be repaired and, if faulty or damaged, they must be
replaced. The blower motor and blower wheel are ser-
viced only as a unit.
DIAGNOSIS AND TESTING - BLOWER MOTOR
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, DISABLE THE AIRBAG SYSTEM BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING
COLUMN, OR INSTRUMENT PANEL COMPONENT
DIAGNOSIS OR SERVICE. DISCONNECT AND ISO-
LATE THE BATTERY NEGATIVE (GROUND) CABLE,
THEN WAIT TWO MINUTES FOR THE AIRBAG SYS-
TEM CAPACITOR TO DISCHARGE BEFORE PER-
FORMING FURTHER DIAGNOSIS OR SERVICE. THIS
IS THE ONLY SURE WAY TO DISABLE THE AIRBAG
SYSTEM. FAILURE TO TAKE THE PROPER PRE-
CAUTIONS COULD RESULT IN AN ACCIDENTAL
AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
For circuit descriptions and diagrams, (Refer to
Appropriate Wiring Information). Possible causes of
an inoperative blower motor include:²Faulty fuse
²Faulty blower motor circuit wiring or wire har-
ness connectors
²Faulty blower motor resistor
²Faulty blower motor relay
²Faulty blower motor switch
²Faulty A/C Heater mode control switch
²Faulty blower motor.
Possible causes of the blower motor not operating
in all speeds include:
²Faulty blower motor switch
²Faulty blower motor resistor
²Faulty blower motor circuit wiring or wire har-
ness connectors.
VIBRATION
Possible causes of blower motor vibration include:
²Improper blower motor mounting
²Improper blower wheel mounting
²Blower wheel out of balance or bent
²Blower motor faulty.
NOISE
To verify that the blower is the source of the noise,
unplug the blower motor wire harness connector and
operate the HVAC system. If the noise goes away,
possible causes include:
²Foreign material in the HVAC housing
²Improper blower motor mounting
²Improper blower wheel mounting
²Blower motor faulty.
