5. RUN THE ACTUATOR CIRCUIT TEST
Turn the ignition off.
Reconnect the A/C Heater Control C1 harness connector.
Turn the ignition on.
With the DRBIII(R) in HVAC, select System Tests and then select Actuator Circuit Test.
Allow the test to run to completion before proceeding.
Q: What message does the DRBIII(R) display?
Same message as from start of test
Replace the A/C Heater Control. Perform BODY VERIFICATION TEST - VER 1. See: Powertrain Management/Computers and Control
Systems/Testing and Inspection/Diagnostic Trouble Code Tests and Associated Procedures/Verification Tests/Body Verification Test
Different message than from start of test
Using the wiring diagram as a guide, inspect the wiring and connectors for conditions causing an intermittent short that set the original test
message. Repair as necessary. If the DRBIII(R) displays a message for a different door driver circuit, return to Step 1 of this diagnostic
procedure. Perform BODY VERIFICATION TEST - VER 1. See: Powertrain Management/Computers and Control Systems/Testing and
Inspection/Diagnostic Trouble Code Tests and Associated Procedures/Verification Tests/Body Verification Test
6. CHECK THE (C34) COMMON DOOR DRIVER CIRCUIT, THE (C32) RECIRCULATION DOOR DRIVER CIRCUIT, THE (C61)
BLEND DOOR DRIVER CIRCUIT, THE (C801) MODE DOOR 1 DRIVER CIRCUIT, THE (C29) MODE DOOR 2 DRIVER
CIRCUIT, & THE (C33) PASSENGER BLEND DOOR DRIVER CIRCUIT FOR A SHORT TO VOLTAGE
Turn the ignition off.
Disconnect the A/C Heater Control C1 harness connector.
Turn the ignition on.
Measure the voltage of the (C34) Common Door Driver Circuit, the (C32) Recirculation Door Driver circuit, the (C61) Blend Door Driver circuit,

Q: Is there any voltage present on any of the circuits?
YES: Repair all door driver circuits with voltage present for a short to voltage. Perform BODY VERIFICATION TEST - VER 1. See:
Powertrain Management/Computers and Control Systems/Testing and Inspection/Diagnostic Trouble Code Tests and Associated
Procedures/Verification Tests/Body Verification Test
NO: Go To 7
7. CHECK THE (C34) COMMON DOOR DRIVER CIRCUIT, THE (C32) RECIRCULATION DOOR DRIVER CIRCUIT, THE (C61)
BLEND DOOR DRIVER CIRCUIT, THE (C801) MODE DOOR 1 DRIVER CIRCUIT, THE (C29) MODE DOOR 2 DRIVER
CIRCUIT, & THE (C33) PASSENGER BLEND DOOR DRIVER CIRCUIT FOR A SHORT TO GROUND
