ACTION
APPLICABILITY
8
Turn the ignition off.
Disconnect the A/C - Heater Control Module C1 harness connector.
Measure the resistance between the Common Door Driver circuit and the applicable
door driver circuit.
Is the resistance above 70.0 ohms?
All
Yes
→ Go To 9
No
→ Reconnect C1. Rerun Recalibration. If DRB displays same fault,
replace A/C-Htr Cntrl in accord with Service Info. If DRBIII
displays a different fault, ck wiring & connectors for cause of
intermittent condition. If no prob found, rerun test from Step 1.
Perform BODY VERIFICATION TEST - VER 1.

Disconnect the A/C - Heater Control Module C1 harness connector.
Remove the applicable door actuator from the A/C - Heater Housing Assembly.
Disconnect the door actuator harness connector.
Measure the resistance of the door driver circuit between the A/C - Heater Control
Module C1 harness connector and the door actuator harness connector.
Is the resistance below 5.0 ohms?
All
Yes
→ Go To 10
No
→ Repair the door driver circuit for an open.
