INSTALLATION
WARNING: Always keep hands and clothing clear
of the wire rope, hook and fairlead opening during
operation and when spooling. Failure to follow
these instructions may result in personal injury or
death.
CAUTION: Wire rope must spool on the winch
drum in the direction indicated.
1. Feed the new wire rope end (3) through the guide
rollers.
2. Attach the flat side of the wire rope end (3) to the
winch drum (1), apply red thread locker to the
threads and install the bolt (2).
3. Wrap the wire rope around the spool approximately
one time, in the direction indicated on the spool.
4. Tighten the bolt to 3 Nꞏm (25 in. lbs.).
5. Arrange the wire rope so it will not kink or tangle
when spooled.
6. Lock the winch drum by rotating the clutch lever (2)
on the winch to “Engage.”
NOTE: Always make sure the clutch is engaged or
disengaged fully.
7. Connect the remote control to the socket.
8. Install the hook (5), the pin (1) and clip (2) to the
end of the wire rope (4).
9. Keep the rope under light tension and spool the
rope back onto the winch drum in even layers.
10. Stop frequently to tighten and straighten the lay-
ers as necessary.
11. Repeat this process until the winch hook (5) is the
same distance from the winch as the full length of
theremotecontrol.
12. Using the hook strap, walk the wire rope towards
the guide rollers, carefully spooling in the remain-
ing wire rope by pulsing the remote control switch.
NOTE: If you do not have the hook strap, use a
length of cord or similar when handling the hook during servicing of the winch.
13. Store the winch hook on the most outboard loop of the tow hook and remove the slack from the wire rope.
When Monitored:
With the ignition on.

MOTOR-BLOWER
DESCRIPTION
The blower motor (1) is used to control the velocity of
air moving through the HVAC housing by spinning the
blower wheel (3) within the HVAC air inlet housing at
the selected speed.
The blower motor is a 12-volt, direct current (DC)
motormountedwithinaplastichousingwithaninte-
gral wire harness connector (2) and squirrel cage-type
blower wheel (3) that is secured to the blower motor
shaft (4). The blower wheel is positioned within the air
inlet housing on the passenger side end of the HVAC
housing.
OPERATION
The blower motor is used to control the velocity of air moving through the HVAC housing by spinning the blower
wheel within the HVAC air inlet housing at the selected speed.
The blower motor will operate whenever the ignition switch is in the Run position and the blower motor control is in
any position except Off. The blower motor receives battery current through the totally integrated power module
(TIPM) whenever the ignition switch is in the Run position.
Blower motor speed is controlled by regulating the ground path through or around the blower motor resistor and
through the blower motor control located within the A/C-heater control.
The blower motor can be accessed for service from underneath the instrument panel.
NOTE: The blower motor is supplied with a 12V feed from the TIPM, through theresistor block, whenever
the ignition switch is in the RUN position. Due to an open circuit conditionwithin the blower motor control
switch the TIPM is UNABLE to detect an OPEN circuit for the blower motor.
The blower motor control system is diagnosed using a scan tool (Refer to 24 -HVAC Electrical Diagnostics for more
information).
The blower motor and blower wheel are factory balanced and cannot be adjusted or repaired. If faulty or damaged,
the blower motor and wheel must be replaced as an assembly.
DIAGNOSIS AND TESTING
BLOWER MOTOR
WARNING: On vehicles equipped with airbags, disable the airbag system before attempting any steering
wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the
negative battery (ground) cable, then wait two minutes for the airbag system capacitor to discharge before
performing further diagnosis or service. Failure to take the proper precautions could result in accidental
airbag deployment and possible personal injury or death.
