Mode Selection Damper Control Motor and Potentiometer Check

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 given procedures.

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: 0.8 (DEF) - 4.8 (FACE) kohms
