    Is there battery voltage? 

    1. YES  - Go to step 5.
    2. NO  - Repair open in the wire between the No. 3 fuse in the driver's under-dash fuse/relay box and the recirculation control motor.
  5. Turn the ignition switch OFF.
  6. Test the recirculation control motor (see Recirculation Control Motor Test  ).

    Is the recirculation control motor OK? 

    1. YES  - Go to step 7.
    2. NO  - Go to step  12.
  7. Disconnect the heater control panel 22P connector.
  8. Check for continuity between the No. 1 and No. 11 terminals of the heater control panel 22P connector and body ground individually.

    Is there any voltage? 

    1. YES  - Repair any short to power in the wire(s) between the heater control panel and the recirculation control motor. This short may also damage the heater control panel. Repair the short to power before replacing the heater control panel.
    2. NO  - Go to step 10.
  10. Turn the ignition switch off.
  11. Check for continuity between the following terminals of the heater control panel 22P connector and the recirculation control motor 7P connector.

    Is there continuity? 

    1. YES  - Check for loose wires or poor connections at the heater control panel 22P connector and at recirculation control motor 7P connector. If the connections are good, substitute a known good heater control panel and recheck. If the symptom/indication goes away, replace the original heater control panel.
    2. NO  - Repair any open in the wire(s) between the heater control panel and the recirculation control motor.
  12. Remove the recirculation control motor (see Recirculation Control Motor Test  ).
  13. Check the recirculation control linkage and doors for smooth movement.

    Do the recirculation control linkage and doors move smoothly? 

    1. YES  - Replace the recirculation control motor.
    2. NO  - Repair the recirculation control linkage or doors.
