INSPECTION
INSPECTION OF AIR SELECTION DAMPER MOTOR
ASSEMBLY
Check that the motor rotates when battery voltage is applied to
the connector on the motor assembly side.
Check also that the motor rotates in the backward direction
when polarity is changed.
Caution
1. Cut off the voltage when the damper is in the RECIR-
CULATION or FRESH position.
2. Cut off the voltage if the motor does not turn when
battery voltage is applied.
INSPECTION OF BLEND AIR DAMPER MOTOR
Check that the motor rotates when battery voltage is applied
across terminals @ and @ of motor assembly side connector.
Check also that the motor turns in the backward direction when
polarity is changed.
Caution
1. Cut off the voltage when the damper is in the MAX.
HOT or MAX. COOL position.
2. Cut off the voltage if the motor does not turn when
battery voltage is applied.
INSPECTION OF BLEND AIR DAMPER POTENTIOMETER
Connect a circuit tester across terminals @ and @ of the motor
assembly connector and check that resistance gradually
changes as the damper is moved from MAX. HOT to MAX.
COOL position.
Standard value
MAX. HOT: Approx. 0.2 kfi
MAX. COOL: Approx. 4.8 klR
INSPECTION OF MODE SELECTION DAMPER MOTOR
Check that the motor turns when battery voltage is applied
across terminals @ and @ of the motor assembly connector.
Check also that the motor turns in the backward direction when
polarity is changed.
Caution
1. Cut off the voltage when the damper is in the DEF. or
FACE position.
2. Cut off the voltage if the motor does not turn when
battery voltage is applied.
INSPECTION OF MODE SELECTION DAMPER POTENTIO-
METER
Connect a circuit tester across terminals @ and @of the motor
assembly connector and check that resistance gradually
changes as the damper is moved from DEF. to FACE position.
Standard value
DEF. position: Approx. 0.2 kfi
FACE position: Approx. 4.8 kfl
