  1. Detach the glove box damper (A), and release both glove box stops (B) by pushing them in, then let glove box (C) hang down.

• 2. Recirculation Control Motor - Test

  1. Disconnect the recirculation control motor connector.

  Incorrectly applying power and ground to the recirculation control motor will damage it. Follow the instructions carefully.

  2. Connect 12 volt battery power to terminal No. 6 of the recirculation control motor, and ground terminal No. 7; the recirculation control motor should run, and stop at FRESH. If it does not, reverse the connections; the recirculation control motor moving to RECIRCULATE side. When the recirculation control motor stops running, disconnect 12 volt 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, go to step 4.
  • If the linkage or door sticks or binds, repair them as needed.

  4. Measure the resistance between terminals No. 1 and No. 3. It should be between 4.2 to 7.8 kΩ

  5. Reconnect the recirculation control motor connector

  6. Turn the vehicle to the ON mode

  7. Using the backprobe set (07SAZ-001000A), measure the voltage between terminals No. 1 and No. 2.

  RECIRCULATE:	About 2.8 V
  FRESH:	About 0.5 V

  8. If either the resistance or the voltage readings are not as specified, replace the recirculation control motor .

• 3. All Removed Parts - Install the parts in the reverse order of removal, and note these items:
