Recirculation Control Motor Test

NOTE: Before testing, check for climate control DTCs (see HOW TO CHECK FOR DTCS WITH THE HDS  ).
  1. Disconnect the 5P connector from the recirculation control motor.
    NOTE: Incorrectly applying power and ground to the recirculation control motor will damage it. Follow the instructions carefully.
  2. Connect battery power to terminal No. 1 of the recirculation control motor, and ground terminal No. 2; the recirculation control motor should run smoothly, and stop at Recirculate. If it does not, reverse the connections; the recirculation control motor should run smoothly, and stop at Fresh. When the recirculation control motor stops running, disconnect battery power immediately.

  3. If the recirculation control motor did not run in step  2, remove it, then check the recirculation control linkage and the door for smooth movement.
    • If the linkage and the door move smoothly, replace the recirculation control motor (see MODE CONTROL MOTOR REPLACEMENT  ).
    • If the linkage or the door stick or bind, repair them as needed.
