TRANSFER CASE VERIFICATION TEST
1.
Disconnect all jumper wires and reconnect all previously disconnected components and connectors.
With the scan tool, select clear Stored DTCs.
Make sure that all accessories are turned off and that the battery is fully charged.
Test drive the vehicle in each Transfer Case range and verify proper operation in each range.
To select or deselect 2WD, AWD or 4HI mode, vehicle speed must be below 88 Kmh(55 mph) with all wheels
at vehicle speed.
Shifts will not take place with a wheel speed difference of greater than 21 Kmh (13 mph) between the front
and rear wheels.
To select or deselect 4LO (if equipped), vehicle speed must be below 5 Kmh (3mph) with the ignition ON and
the transmission in neutral (auto trans) or the clutch pedal pressed (man trans).
To select or deselect Transfer Case Neutral, vehicle speed must be 0 Kmh (0 mph) with the ignition ON,
engine OFF, the brake pedal applied, and the transmission in neutral (autotrans) or the clutch pedal pressed
(man trans). Press the Neutral button (if equipped) on the Transfer Case Selector Switch until the Neutral Indi-
cator is illuminated.
WARNING: Apply the parking brake. The vehicle may roll with the Transfer Case in neutral.
To verify that the Transfer Case is in Neutral, shift the automatic transmission into reverse and release the
brake pedal for three seconds or shift the manual transmission into gear andslowlyreleasetheclutchpedal.
There should be no vehicle movement if the Transfer Case is in Neutral.
With the scan tool, select View DTCs in the Totally Integrated Power Module(TIPM) and in the Instrument Cluster.
Are there any DTCs present in the Totally Integrated Power Module (TIPM) orin the Instrument Cluster?
Ye s>>
Return to the symptom list and perform the appropriate diagnostic test.
No>>
Repair is complete.

WARNING
SAFETY PRECAUTIONS AND WARNINGS
WARNING: Use an OSHA approved breathing filter when spraying paint or solvents in a confined area. Per-
sonal injury can result.
Avoidprolongedskincontactwithpetroleumoralcohol–basedcleaningsolvents. Personal injury can
result.
Do not stand under a hoisted vehicle that is not properly supported on safety stands. Personal injury can
result.
CAUTION: When holes must be drilled or punched in an inner body panel, verify depth of space to the outer
body panel, electrical wiring, or other components. Damage to vehicle canresult.
Do not weld exterior panels unless combustible material on the interior ofvehicle is removed from the
repair area. Fire or hazardous conditions, can result.
Always have a fire extinguisher ready for use when welding.
Disconnect the negative (-) cable clamp from the battery when servicing electrical components that are
live when the ignition is OFF. Damage to electrical system can result.
Do not use abrasive chemicals or compounds on painted surfaces. Damage to finish can result.
Do not use harsh alkaline based cleaning solvents on painted or upholstered surfaces. Damage to finish
or color can result.
Do not hammer or pound on plastic trim panel when servicing interior trim. Plastic panels can break.
DIAGNOSIS AND TESTING
WAT E R L E A K S
Water leaks can be caused by poor sealing, improper body component alignment, body seam porosity, missing
plugs, or blocked drain holes. Centrifugal and gravitational force can cause water to drip from a location away from
the actual leak point, making leak detection difficult. All body sealing points should be water tight in normal wet-
driving conditions. Water flowing downward from the front of the vehicle should not enter the passenger or luggage
compartment. Moving sealing surfaces will not always seal water tight under all conditions. At times, side glass or
door seals will allow water to enter the passenger compartment during highpressure washing or hard driving rain
(severe) conditions. Overcompensating on door or glass adjustments to stop a water leak that occurs under severe
conditions can cause premature sealwear and excessive closing or latching effort. After completing a repair, water
test vehicle to verify leak has stopped before returning vehicle to use.
VISUAL INSPECTION BEFORE WATER LEAK TESTS
Verify that floor and body plugs are in place, body drains are clear, and body components are properly aligned and
sealed. If component alignment or sealing is necessary, refer to the appropriate section of this group for proper
procedures.
WATER LEAK TESTS
WARNING: Do not use electric shop lights or tools in water test area. Personal injury can result.
When the conditions causing a water leak have been determined, simulate the conditions as closely as possible.
Ifaleakoccurswiththevehicleparkedinasteadylightrain,floodtheleak area with an open-ended garden
hose.
If a leak occurs while driving at highway speeds in a steady rain, test the leak area with a reasonable velocity
stream or fan spray of water. Direct the spray in a direction comparable to actual conditions.
If a leak occurs when the vehicle is parked on an incline, hoist the end or sideofthevehicletosimulatethis
condition. This method can be used when the leak occurs when the vehicle accelerates, stops or turns. If the
leak occurs on acceleration, hoist the front of the vehicle. If the leak occurs when braking, hoist the back of the

Theory of Operation
The A/C Heater Control drives the Passenger Blend Door Actuator via the (C33) Passenger Blend Door Driver cir-
cuit and the (C34) Common Door Driver circuit. All of the door actuators share the (C34) Common Door Driver
circuit. Inside the A/C Heater Control, each door actuator has its own unique driver, but all share a single common
door driver circuit. Due to the shared circuitry similar DTCs can set at thesame time for multiple actuators depend-
ing upon the type of short, its location, and the direction the actuator is moving when the short is present.
When Monitored:
When the Actuator DTC Detection Test is executed.
Set Condition:
If the (C33) Passenger Blend Door Driver circuit is shorted to ground.
Possible Causes
(C33) PASSENGER BLEND DOOR DRIVER CIRCUIT SHORTED TO GROUND
(C33) PASSENGER BLEND DOOR DRIVER CIRCUIT SHORTED TO OTHER DOOR DRIVER CIRCUIT(S)
