Rear Vent Control Motor Test

NOTE: Before testing, check for climate control DTCs (see HOW TO CHECK FOR DTCS WITH THE HDS ).

Disconnect the 5P connector from the rear vent control motor.
NOTE: Incorrectly applying power and ground to the rear vent control motor will damage it. Follow the instructions carefully.
Connect battery power to terminal No. 1 of the rear vent control motor, and ground terminal No. 2; the rear vent control motor should run smoothly, and stop at Shut. If it does not, reverse the connections; the rear vent control motor should run smoothly, and stop at Rear Vent. When the rear vent control motor stops running, disconnect battery power immediately.

If the rear vent control motor did not run in step 2, remove it, then check the rear vent control linkage and the door for smooth movement.
- If the linkage and the door move smoothly, replace the rear vent control motor (see PASSENGER'S COOL VENT CONTROL MOTOR REPLACEMENT ).
- If the linkage or the door sticks or binds, repair them as needed.
