WATER DRAINAGE AND WIND NOISE DIAGNOSIS
The sliding glass panel is designed to seal water
entry with a snug fit between the roof and the seal.
The fit can be checked by inserting a piece of paper
between the roof and the seal. The piece of paper
should have some resistance when pulled out when
the glass panel is in the closed position. Excessive
wind noise could result if the gap clearances are
exceeded. The sunroof glass panel may need to be
adjusted. Refer to Sunroof Glass Panel Adjustment
for proper procedures.
Adequate drainage is provided by a drain trough in
the sunroof housing which encircles the sliding glass
panel and leads to drain hoses. If a wet headliner or
other water leak complaints are encountered, before
performing any adjustments, first ensure that the
drainage system is not plugged or disconnected. Use
a pint container to pour water into the sunroof hous-
ing drain trough. If water flow is restricted in any of
the four drain holes, use compressed air to blow out
any material plugging the drain system. Retest sys-
tem again.
To further check for a disconnected drain hose:
(1) Remove A-pillar trim, sun visors, and map
lamps/mini console.
(2) Remove sunroof opening trim lace. Refer to
Sunroof Opening Trim Lace.
NOTE: Care must be taken not to fold or kink the
headliner upon removal.
(3) Lower headliner as necessary to gain access to
sunroof housing drain tubes. Refer to Headlining
Removal and Installation for proper procedures.
(4) Repair as necessary.

(2) Disconnect negative battery cable.
(3) Remove headliner (Refer to 23 - BODY/INTE-
RIOR/HEADLINER - REMOVAL).
(4) Disconnect the drain hose from the sunroof
housing (Fig. 1).
(5) Drain any liquid from hose connection, repair
as necessary.

AIR OUTLETS
DESCRIPTION
Based upon the system mode selected, conditioned
air can exit the rear HVAC housing through one or a
combination of the two main housing outlets: air con-
ditioner, or heater. Once the conditioned air exits the
unit housing, it is directed through molded plastic
ducts to the various outlets in the vehicle interior.
These outlets and their locations are as follows:
²Floor Outlets- Three floor outlets with fixed
vanes are located in the right quarter trim panel,
near the floor. These outlets distribute air from the
rear floor heat duct to the intermediate and rear seat
occupants. The floor outlets are integral to the right
quarter trim panel and, if faulty or damaged, the
quarter trim panel must be replaced.
²Overhead Outlets- Four (two right side and
two left side) fully adjustable outlets along the roof
rails distribute air from the rear distribution duct
and the headliner ducts to the intermediate and rear
seat occupants. The headliner ducts are integral to
the headliner panel. Each overhead outlet is housed
in a headliner bezel. The two forward headliner
bezels also feature a courtesy lamp, a fold-away coat
hook, and a fold-away assist handle. The overhead
outlets can be removed from the headliner bezels
individually for service replacement.
REMOVAL
(1) Using a trim stick or another suitable wide
flat-bladed tool, gently pry the thumb wheel end of
the overhead outlet away from the pivot pin in the
headliner bezel until one end of the outlet is released
(Fig. 1).(2) Pull the opposite end of the overhead outlet
away from its pivot pin in the headliner bezel until
that end of the outlet is released.
(3) Remove the overhead outlet from the opening
in the headliner bezel.
INSTALLATION
(1) Position the overhead outlet into the opening in
the headliner bezel.
(2) Slide the non-thumb wheel end of the outlet
onto the pivot pin in the headliner bezel. Using hand
pressure, push the thumb wheel end outboard onto
the pivot pin until it fully seats.

(4) Open both the suction and discharge valves,
then open the charge valve to allow the heated
refrigerant to flow into the system.
(5) When the transfer of refrigerant has stopped,
close both the suction and discharge valves.
(6) If all of the refrigerant charge did not transfer
from the dispensing device, open all of the windows
in the vehicle and set the heater-air conditioner con-
trols so that the compressor is engaged and the
blower motor is operating at its lowest speed setting.
Run the engine at a steady high idle (about 1400
rpm). If the compressor will not engage, test the com-
pressor clutch control circuit and repair as required.
(7) Open the suction valve to allow the remaining
refrigerant to transfer to the refrigerant system.
WARNING: TAKE CARE NOT TO OPEN THE DIS-
CHARGE (HIGH PRESSURE) VALVE AT THIS TIME.
(8) Close the suction valve and test the system
performance. (Refer to 24 - HEATING & AIR CON-
DITIONING - STANDARD PROCEDURE - A/C PER-
FORMANCE TEST).
(9) Disconnect the charging station and manifold
gauge set from the refrigerant system service ports.
(10) Reinstall the caps onto the refrigerant system
service ports.
(11) Run the HVAC Control Cooldown test to ver-
ify proper operation(Refer to 24 - HEATING & AIR
CONDITIONING - DIAGNOSIS AND TESTING).
A/C COMPRESSOR
DESCRIPTION
A/C COMPRESSOR
Vehicles equipped with the 2.4L gasoline, 2.5L die-
sel, 2.8L diesel and 3.3L gasoline engines with the
front heating-A/C system only, use the Denso 10S17
A/C compressor. Vehicles equipped with the 3.3L and
the 3.8L gasoline engines with the optional rear heat-
ing-A/C system use the Denso 10S20 A/C compressor.
Both A/C compressors include an integral high pres-
sure relief valve. The A/C compressor is secured to a
mounting bracket on the 2.4L gasoline engine and
directly to the cylinder block on the 2.5L diesel, 2.8L
diesel, 3.3L gasoline and 3.8L gasoline engines.
HIGH PRESSURE RELIEF VALVE
A high pressure relief valve is located on the rear
of the A/C compressor. This mechanical valve is
designed to vent refrigerant from the A/C system to
protect against damage to the compressor and other
system components, caused by condenser air flow
restriction or an overcharge of refrigerant.
OPERATION
A/C COMPRESSOR
The A/C compressor is driven by the engine
through an electric clutch, drive pulley and belt
arrangement. The compressor is lubricated by refrig-
erant oil that is circulated throughout the refrigerant
system with the refrigerant.
The compressor draws in low-pressure refrigerant
vapor from the evaporator through its suction port. It
then compresses the refrigerant into a high-pressure,
high-temperature refrigerant vapor. The compressor
pumps the high-pressure refrigerant vapor to the
condenser through the compressor discharge port.
The compressor cannot be repaired. If faulty or
damaged, the entire compressor assembly must be
replaced. The compressor clutch, pulley and clutch
coil are available for service.
HIGH PRESSURE RELIEF VALVE
The high pressure relief valve vents the system
when a discharge pressure of 3445 to 4135 kPa (500
to 600 psi) or above is reached. The valve closes
when a minimum discharge pressure of 2756 kPa
(400 psi) is reached.
The high pressure relief valve vents only enough
refrigerant to reduce the system pressure, and then
re-seats itself. The majority of the refrigerant is con-
served in the system. If the valve vents refrigerant, it
does not mean that the valve is faulty.
The high pressure relief valve is a factory-cali-
brated unit. The valve cannot be adjusted or
repaired, and must not be removed or otherwise dis-
turbed. The valve is only serviced as a part of the
compressor assembly.
DIAGNOSIS AND TESTING
A/C COMPRESSOR NOISE DIAGNOSIS
Excessive noise while the air conditioning compres-
sor is operating can be caused by loose compressor
mounts, a loose compressor clutch, or high operating
pressures in the refrigerant system. Verify compres-
sor drive belt condition, proper compressor mounting,
correct refrigerant charge level, and compressor head
pressure before compressor repair is performed.
With the close tolerances within the compressor, it
is possible to experience a temporary lockup. The
longer the compressor is inactive, the more likely the
condition is to occur. This condition is the result of
normal refrigerant migration within the refrigerant
system caused by ambient temperature changes. The
refrigerant migration may wash the refrigerant oil
out of the compressor.
