Recirculation Control Motor Test

Recirculation Control Motor Test

NOTE: Before testing, check for HVAC DTCs.

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 the No. 5 terminal of the recirculation control motor, and ground the No. 1 and No. 2 terminals; the recirculation control motor should run smoothly. To avoid damaging the recirculation control motor, do not reverse power and ground. Disconnect the No. 1 or No. 2 terminals from ground; the recirculation control motor should stop at Fresh (when the No. 1 terminal is disconnected) or Recirculate (when the No. 2 terminal is disconnected). Don't cycle the recirculation control motor for a long time.
3. If the recirculation control motor did not run in step 2, remove it, then check the recirculation control linkage and doors for smooth movement.
- If the linkage and doors move smoothly, replace the recirculation control motor.
- If the linkage or doors stick or bind, repair them as needed.
