POTENTIOMETER CHECK
While checking the air mix damper control motor, measure the
resistances between terminals numbers 3 and 5 as well as
numbers 3 and 7. At this time, the resistances should change
gradually within the standard value.

Standard value: 1.2

− 4.8 k

MODE SELECTION DAMPER CONTROL MOTOR CHECK

CAUTION

Do not apply battery voltage when the damper is in the
FACE or DEF position.
Check the mode selection damper control motor by the follow-
ing procedures.

HEATER WATER TEMPERATURE SENSOR CHECK
NOTE: The temperature conditions when checking should not
exceed the range shown in the diagram.
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.
