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

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.
