Recirculation Control Motor Test

NOTE: Before testing, check for HVAC DTCs (see GENERAL TROUBLESHOOTING INFORMATION ).

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.
Connect battery power to the No. 1 terminal of the recirculation control motor, and ground the No. 2 terminal; the recirculation control motor should run, and stop at Recirculate. If it doesn't, reverse the connections; the recirculation control motor should run, and stop at Fresh.

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