AIR MIXING DAMPER CONTROL MOTOR CHECK
Do not apply battery voltage when the damper is in the
MAX COOL or MAX HOT position.
Check the air mix damper control motor by the following proce-
dures.
.
POTENTIOMETER CHECK
While checking the air mix damper control motor, measure the
resistances between terminals numbers 3 and 5 and between
numbers 3 and 7. At this time, the resistances should change
gradually within the standard value.
Standard value: 1.7 (MAX HOT)
5.0 (MAX COOL) k
AIR THERMO SENSOR INSPECTION
.Measure the resistance between connector terminals 1 and 2
under at least two different temperatures. The resistance val-
ues should generally match those in the graph.
NOTE: The temperature at the check should not exceed the
range in the graph. LEVER POSITION BATTERY

INTERIOR TEMPERATURE SENSOR CHECK
When the resistance between the sensor terminals is mea-
sured under two or more temperature conditions, the resis-
tance should approximately satisfy the illustrated values.
NOTE:
The temperature conditions when checking should not
exceed the range shown in the diagram.
.
PHOTO SENSOR CHECK
1. Connect diagnostic tool , and check the data list of the
photo sensor. (Refer to P.55-133)
2. Check that the displayed value changes when you cover
the photo sensor with your hands.

AMBIENT AIR TEMPERATURE SENSOR CHECK
The ambient air temperature sensor should be checked
without removing it from bumper. If the sensor is removed,
damage will occur to clip rendering it unserviceable.
Measure the resistance between the sensor terminals under at
least two temperatures. The resistance values should meet the
values shown.
NOTE: The temperature should be within the shown range.
