Air Door Actuator / Motor: Testing and Inspection
Driver's Mode Control Motor
Driver's Mode Control Motor Test
NOTE: Before testing, check for HVAC DTCs.
1. Disconnect the lop connector from the driver's mode control motor.
NOTE: Incorrectly applying power and ground to the driver's mode control motor will damage it. Follow the instructions carefully.
2. Connect battery power to the No.2 terminal of the ci river's mode control motor, and ground the No.1 terminal; the driver's mode control motor
should run smoothly, and stop at Vent. If it doesn't, reverse the connections; the driver's mode control motor should run smoothly, and stop at
Defrost. When the driver's mode control motor stops running, disconnect battery power immediately.
3. If the driver's mode control motor did not run in step 2, remove it, then check the driver's mode control linkage and doors for smooth movement.
-
If the linkage and doors move smoothly, replace the driver's mode control motor.
-
If the linkage or doors stick or bind, repair them as needed.
-
If the driver's mode control motor runs smoothly, go to step 4.
4. Use a digital multimeter with an output of 1 mA or less at the 20 kOhm) range. With the driver's mode control motor running as instep 2, check
for continuity between the No.6, 7, 8 and 9 terminals and the No.10 terminal individually. There should be continuity for a moment at each
terminal as the motor moves past the switch's terminal.
5. If there is no continuity for a moment at each terminal, replace the driver's mode control motor.
