-Repair a short to body ground in the wire(s) between the HVAC control unit and the recirculation control motor.
NO
-Go to step 9.
9. Turn the ignition switch to ON (II), and check the same terminals for voltage between each terminal and body ground.
HVAC CONTROL UNIT 24P CONNECTOR

Is there any voltage? YES
-Repair a short to power in the wire(s) between the HVAC control unit and the recirculation control motor. This short may also damage the HVAC control unit. Repair a short to power before replacing the HVAC control unit.
NO
-Go to step 10.
10. Turn the ignition switch to LOCK (0).
11. Check for continuity between the following terminals of the HVAC control unit 24P connector and the recirculation control motor 7P connector.

Is there continuity? YES
-Check for loose wires or poor connections at the HVAC control unit 24P connector, and at the recirculation control motor 7P connector. If the connections are good, substitute a known-good HVAC control unit, and recheck. If the symptom/indication goes away, replace the original HVAC control unit (see page 21-65).
NO
-Repair an open in the wire(s) between the HVAC control unit and the recirculation control motor.
