12 Turn the ignition off.
Ensure the C202/3 inline connector is connected at this time.
With the DRBIII , erase DTC's.
Disconnect the BCM C1 harness connector.
Backprobe one voltmeter lead to the Blend Air Door Driver ckt in the BCM C1
connector and the other to chassis ground.
Reconnect the BCM C1 harness connector.
Turn the ignition on.
Move the temperature control from cold (LO) to hot (HI) while observing the
voltmeter.
Did the voltage ever go above 10.0 volts?
Yes → Go To 13
→ Replace the Body Control Module (blend air door driver open).
No
