RECIRC DOOR OUTPUT SHORTED TO BATTERY —
TEST
3 Disconnect the Body Control Module C1 harness connector.
Turn the ignition on.
Measure the voltage of the Recirculation Door Driver circuit.
Is the voltage above 10.0 volts?
Yes → Repair the Recirculation Door Driver circuit for a short to battery.
→ Go To 4
No
4 Disconnect the Body Control Module C1 harness connector.
Turn the ignition on.
Measure the voltage of the Common Door Driver circuit.
Is the voltage above 10.0 volts?
Yes → Repair the Common Door Driver circuit for a short to battery.
→ Go To 5
No
5 Turn the ignition off.
Disconnect the Body Control Module C1 harness connector.
Measure the resistance between the Common Door Driver (cavity 10), the Mode Door
Driver (cav 9), the Recirc Door Driver (cav 2) and the Blend Door Driver (cav 3) in the
BCM C1 connector.
Measure the resistance between the Mode Door Driver (cavity 9), the Recirc Door
Driver (cav 2) and the Blend Door Driver (cav 3) in the BCM C1 connector.
Measure the resistance between the Blend Door Driver (cavity 3) and the Recirc Door
Driver (cav 2) in the BCM C1 connector.
Is the resistance below 5.0 ohms between any of the door driver circuits?
Yes → Go To 6
→ Replace the Body Control Module.
No
6 Disconnect the Body Control Module C1 harness connector.
Disconnect the Blend Door Actuator harness connector.
Measure the resistance between the Blend Air Door Driver circuit (cavity 3) and the
other driver circuits (cavities 2, 9 and 10) in the BCM C1 connector.
Is the resistance below 5.0 ohms between any of the driver circuits?
Yes → Go To 7
→ Replace the Blend Door Actuator.
No
