Driver's Air Mix Control Motor Test

NOTE: Before testing, check for HVAC DTCs.

1. Disconnect the 5P connector from the driver's air mix control motor.

NOTICE:
Incorrectly applying power and ground to the driver's air mix control motor will damage it. Follow the instructions carefully.

2. Connect battery power to the No. 1 terminal of the driver's air mix control motor, and ground the No. 2 terminal; the driver's air mix control motor should run, and stop at Max Cool. If it doesn't, reverse the connections; the driver's air mix control motor should run, and stop at Max Hot.






3. If the driver's air mix control motor did not run in step 2, remove it, then check the driver's air mix control linkage and door for smooth movement.
- If the linkage and door move smoothly, replace the driver's air mix control motor.
- If the linkage or door sticks or binds, repair them as needed.
