Air Door Actuator / Motor: Testing and Inspection
Component Test
Function Control Motor Test
1. Measure the resistance between the No. 3 and 5 terminals.
-
Resistance: 4 k ohms
2. Check the motor operation by briefly connecting the battery (6 V) positive to the No. 2 terminal and negative to the No. 1 terminal.
3. Reverse the wires to be sure the motor will run in both directions.
CAUTION: Be sure to disconnect the battery from the motor as soon as the motor has started. Failure to do so will damage the motor.
4. Connect a battery to the motor (positive to No. 2 and negative to No. 1), and measure the resistance between the terminals No. 4 and No. 5.
Resistance should be approximately 1.2 k ohms at VENT and 4.0 k ohms at DEF. Also check the resistances with the battery polarity reversed.
