5 Turn the ignition off.
Ensure the C202 (manual A/C) or C203 (ATC) in-line connector (HVAC) located in the
center of the instrument panel above the accelerator pedal is connected.
Disconnect the Body Control Module C1 harness connector
Disconnect the Body Control Module C2 harness connector.
Disconnect the Blend Door Actuator harness connector.
Measure the resistance between the 5 volt supply circuit in the BCM C2 connector
and the sensor ground circuit in the BCM C1 connector.
Is the resistance below 2000.0 ohms?
Yes → Go To 6
→ Replace the Blend Door Actuator.
No
6 Turn the ignition off.
Ensure the C202 (manual A/C) or C203 (ATC) in-line connector (HVAC) located in the
center of the instrument panel above the accelerator pedal is connected.
Disconnect the Body Control Module C1 harness connector
Disconnect the Body Control Module C2 harness connector.
Disconnect the Mode Door Actuator harness connector.
Measure the resistance between the 5 volt supply circuit in the BCM C2 connector
and the sensor ground circuit in the BCM C1 connector.
Is the resistance below 2000.0 ohms?
Yes → Repair the 5 volt supply circuit for a short to the sensor ground
→ Replace the Mode Door Actuator.
No
