DIAGNOSIS AND TESTING - IN-CAR SENSOR
ASPIRATOR MOTOR
(1) Perform air flow test to check the aspirator
motor assembly.
(a) Turn ignition to the ON position and push
the OFF button to stop the ATC system airflow.
This will make it easier to observe paper in step b.
(b) Place a small piece of newspaper in front of
the aspirator motor opening on the ATC control. If
the paper sticks to the opening, the in-car sensor
aspirator motor is operating properly. The piece of
paper should be only large enough to cover the
grille opening (Fig. 15).

REMOVAL
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.
If the ATC in-car temperature sensor (fault 26) is
verified to be bad, or if there is a problem with the
in-car sensor aspirator motor, then the ATC control
must be replaced. (Refer to 24 - HEATING & AIR
CONDITIONING/CONTROLS/A/C HEATER CON-
TROL - REMOVAL)
BLEND DOOR ACTUATOR
DESCRIPTION
The blend door actuator is an electric motor which
mechanically positions the blend door. A potentiome-
ter in the actuator allows the BCM (for both manual
and ATC systems) to know the exact position of the
blend door at all times. The blend door actuator is
not serviceable and must be replaced if found to be
defective.
