Recirculation Control Motor Test (Without Climate Control (08-10 Models With M/T And 08-09 Models 2-Door With A/T))

Recirculation Control Motor Test

Special Tools Required

- Backprobe Set 07SAZ-001000A (2)

'08-11 models with M/T and '08-09 models 2-door with A/T

NOTE: Before testing the motor, check for HVAC DTCs How To Troubleshoot The Heating And A/C Systems (Without Climate Control).

1. Disconnect the 7P connector from the recirculation control motor.

NOTICE
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, and stop at Fresh. If it doesn't, reverse the connections; the recirculation control motor should run, and stop at Recirculate. 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 door for smooth movement.

- If the linkage and door move smoothly, replace the recirculation control motor Recirculation Control Motor Replacement.
- If the linkage or door sticks or binds, repair them as needed.
- If the recirculation control motor runs smoothly, go to step 4.

4. Measure the resistance between terminals No. 5 and No. 7 of the recirculation control motor. It should be between 4.2 and 7.8 kOhms.

5. Reconnect the recirculation control motor 7P connector, then turn the ignition switch to ON (II).

6. Using the backprobe set (07SAZ-001000A), measure the voltage between terminals No. 3 and No. 7 of the 7P connector.





7. If either the resistance or the voltage readings are not as specified, replace the recirculation control motor Recirculation Control Motor Replacement.
