Recirculation Control Motor Test
- Disconnect the 7P connector from the recirculation control motor.NOTE: Incorrectly applying power and ground to the recirculation control motor will damage it. Follow the instructions carefully.
- Connect battery power to terminal No. 1 of the recirculation control motor, and ground either terminal No. 5 or terminal No, 7. The motor should run smoothly to the Fresh position (terminal No. 5 connected to ground), or the Recirculate position (terminal No. 7 connected to ground). Disconnect battery power immediately when the motor stops running.NOTE: Do not reverse the power and ground connections, or leave the recirculation control motor connected to power and ground after it has stopped running. These actions will damage the motor.
- 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.
