SUNROOF
DESCRIPTION
WARNING: Keep fingers and other body parts out
of sunroof opening at all times.
The sun roof features consists of: (Fig. 1)
²Sun roof glass
²Sun roof sun shade
The sunroof power sliding glass panel and sun-
shade can be positioned anywhere along its travel,
rearward of glass panel front edge.
The sunroof is electrically operated from a switch
located in the overhead console. To operate the sun-
roof the ignition switch must be in the Accessory or
On/Run position. Both switchs are a rocker style
design that open or close the sunroof. When pressing
and releasing the open button once, the sunroof will
express open to the comfort stop and the wind deflec-
tor will raise. If the button is pressed a second time,
the sunroof will continue to open to full travel unless
the button is released, at which time it will stop in
that position. Pressing and holding the close button
will close the sunroof. If the close button is released
before the glass fully closes, the sunroof will stop in
that position. The vent switch operates in a similar
manor. The sunroof will also operate for up to fifteenminutes after the ignition key is turned off for cus-
tomer comfort and convenance while parking.
DIAGNOSIS AND TESTING - SUNROOF
Refer to Sunroof Diagnostic Chart for possible
causes. Before beginning sunroof diagnostics verify
that all other power accessories are in proper operat-
ing condition. If not, a common electrical problem
may exist. Refer to Wiring Diagrams, in this publica-
tion for circuit, splice and component descriptions.
Check the condition of the circuit protection (20 amp
circuit breaker in the Junction Block). Inspect all
wiring connector pins for proper engagement and
continuity. Check for battery voltage at the power
sunroof controller, refer to Wiring Diagrams, for cir-
cuit information. If battery voltage of more than 10
volts is detected at the controller, proceed with the
following tests (the controller will not operate at less
than 10 volts).
Before beginning diagnosis for wind noise or water
leaks, verify that the problem was not caused by
releasing the control switch before the sunroof was
fully closed. The sunroof module has a water-man-
agement system. If however, the sunroof glass is in a
partial closed position, high pressure water may be
forced beyond the water management system bound-
aries and onto the headlining.

MECHANICAL PROBLEMS
Possible causes of insufficient heat due to mechan-
ical problems are as follows:
²Obstructed cowl air intake.
²Obstructed heater system outlets.
²Blend door not functioning properly.
TEMPERATURE CONTROL
If the heater outlet air temperature cannot be
adjusted with the temperature control knob on the
A/C-heater control panel, the following could require
service:
²Blend door binding.²Faulty blend door actuator.
²Faulty A/C-heater control.
²Faulty related wiring harness or connectors.
²Improper engine coolant temperature.

²The normally open terminal (87) provides a bat-
tery current output to the compressor clutch coil
through the compressor clutch relay output circuit
only when the compressor clutch relay coil is ener-
gized.
²The normally closed terminal (87A) is not con-
nected to any circuit in this application, but provides
a battery current output only when the compressor
clutch relay coil is de-energized.
The A/C compressor clutch relay cannot be
repaired and, if faulty or damaged, it must be
replaced. Refer to the appropriate wiring information
for diagnosis and testing of the micro-relay and for
complete HVAC wiring diagrams.
REMOVAL
(1) Disconnect and isolate the negative battery
cable.
(2) Remove the cover from the integrated power
module (IPM) (Fig. 8).
(3) Refer to the fuse and relay layout map on the
inner surface of the IPM cover for A/C compressor
clutch relay identification and location.
(4) Remove the A/C compressor clutch relay from
the IPM.
INSTALLATION
(1) Refer to the fuse and relay layout map on the
inner surface of the integrated power module (IPM)cover for A/C compressor clutch relay identification
and location.
(2) Position the A/C compressor clutch relay into
the proper receptacle in the IPM.
(3) Align the A/C compressor clutch relay termi-
nals with the terminal cavities in the IPM receptacle.
(4) Push down firmly on the A/C compressor clutch
relay until the terminals are fully seated in the ter-
minal cavities in the IPM receptacle.
(5) Install the cover onto the IPM.
(6) Reconnect the negative battery cable.
A/C HEATER CONTROL
DESCRIPTION
The A/C-heater control is located at the center of
the instrument panel and uses electrical controls.
These controls provide the vehicle operator with a
number of setting options to help control the climate
and comfort within the vehicle. Refer to the owner's
manual in the vehicle glove box for more information
on the suggested operation and use of these controls.
The A/C-heater control cannot be repaired. If faulty
or damaged, the entire unit must be replaced. The
control knobs and the illumination lamps are avail-
able for service replacement.
STANDARD PROCEDURE - A/C-HEATER
CONTROL CALIBRATION
The A/C-heater control module must be recali-
brated each time an actuator motor or the control
module is replaced. If the vehicle is so equipped, the
calibration procedure also includes rear HVAC posi-
tions for each actuator motor.
(1) Turn the ignition switch to the On position.
(2) If equipped with the manual temperature con-
trol (MTC) system, press and hold the Rear Wipe/
Wash and Recirculation buttoms for at least five
seconds. If equipped with the automatic temperature
control (ATC) systen, simultaneously press and hold
the Power and Recirculation buttons on the A/C-
heater control for at least five seconds. The MTC
A/C-heater control Rear Wipe/Wash Light Emitting
Diode (LED) and Recirculation LED, or the ATC A/C-
heater control Delay and Recirculation graphics will
begin to flash when the calibration procedure has
begun.
(3) The calibration procedure should take less than
two minutes to complete for the manual A/C-heater
control, and less than twenty seconds for the ATC
A/C-heater control. When the LEDs or graphics stop
flashing, the calibration procedure is complete.
(4) If the LEDs or graphics continue to flash
beyond the two minute (manual) or twenty second
(ATC) calibration time, it indicates that the A/C-

normally open contact point. When the relay coil is
de-energized, spring pressure returns the movable
contact point back against the fixed normally closed
contact point. The resistor or diode is connected in
parallel with the relay coil in the relay, and helps to
dissipate voltage spikes and electromagnetic interfer-
ence that can be generated as the electromagnetic
field of the relay coil collapses.
The blower motor relay terminals are connected to
the vehicle electrical system through a receptacle in
the Integrated Power Module (IPM). The inputs and
outputs of the blower motor relay include:
²The common feed terminal (30) receives a bat-
tery current input from the battery through a B(+)
circuit at all times.
²The coil ground terminal (85) receives a ground
input through the front/rear blower motor relay con-
trol circuit only when the FCM electronically pulls
the control circuit to ground.
²The coil battery terminal (86) receives a battery
current input from the battery through a B(+) circuit
at all times.
²The normally open terminal (87) provides a bat-
tery current output to the blower motor resistor
(manual heater-A/C control) or blower power module
(automatic heater-A/C control) through a fuse in the
IPM on the fused front blower motor relay output cir-
cuit only when the blower motor relay coil is ener-
gized.
²The normally closed terminal (87A) is not con-
nected to any circuit in this application, but provides
a battery current output only when the blower motor
relay coil is de-energized.
Refer to the appropriate wiring information for
diagnosis and testing of the micro-relay and for com-
plete HVAC wiring diagrams.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Unlatch and remove the cover from the Inte-
grated Power Module (IPM) (Fig. 13).
(3) See the fuse and relay layout map molded into
the inner surface of the IPM cover for front blower
motor relay identification and location.(4) Remove the front blower motor relay from the
IPM by pulling the relay straight up.
INSTALLATION
(1) Refer to the fuse and relay layout map on the
inner surface of the integrated power module (IPM)
cover for front blower motor relay identification and
location.

with the terminal cavities in the IPM receptacle.
(4) Push down firmly on the front blower motor
relay until the terminals are fully seated in the ter-
minal cavities in the IPM receptacle.
(5) Install the cover onto the IPM.
(6) Reconnect the negative battery cable.
