(15) Clean access urethane from exterior with
MopartSuper Kleen or equivalent.
(16) Apply 150 mm (6 in.) lengths of 50 mm (2 in.)
masking tape spaced 250 mm (10 in.) apart to hold
molding in place until urethane cures.
(17) Engage wire connectors to windshield
defroster grid.
(18) Install A-pillar trim panels.
(19) Install cowl cover and wipers.
(20) Install inside rear view mirror.
(21) After urethane has cured, remove tape strips
and water test windshield to verify repair.SLIDING DOOR GLASS
REMOVAL
The temperature of the vehicle should be at least
21É C (70É F) before removing the stationary quarter/
sliding door glass. Butyl sealer becomes more pliable
at high temperatures.
(1) Remove interior trim as necessary to gain
access attaching locations on back of glass.
(2) Remove nuts holding stationary glass to fence.
(3)
Using razor knife, cut butyl sealer holding glass
to fence from between the mounting studs (Fig. 4).
(4) Push glass from opening.
INSTALLATION
The temperature of the vehicle should be at least
21É C (70É F) before removing the stationary quarter/
sliding door glass. Butyl sealer becomes more pliable
at high temperatures.
The stationary glass fence should be cleaned of all
old butyl sealer.
(1) Applya6mm(0.25 in.) butyl tape around
perimeter of glass assembly encapsulation track.
Ensure that the butyl tape is wrapped around the
mounting studs.
(2) Place the glass into the opening and insert
mounting studs through holes in fence.
(3) Install nuts to hold stationary glass to fence.
CAUTION: Tighten nuts to 3.4 N´m (30 in. lbs.)
torque in the sequence indicated. Do not over
torque, or glass breakage may result (Fig. 4).
(4) Install interior trim. (Refer to 23 - BODY/
DOORS - SLIDING/TRIM PANEL - INSTALLATION)
(5) Verify alignment and flushness.

The evaporator temperature sensor cannot be
adjusted or repaired and, if faulty or damaged, it
must be replaced.
OPERATION
The evaporator temperature sensor monitors the
temperature of the evaporator through its connection
to the top of the expansion valve. The sensor will
change its internal resistance in response to the tem-
peratures it monitors. The heater-A/C control module
is connected to the sensor through a sensor ground
circuit and a sensor signal circuit. As the evaporator
temperature increases, the resistance of the sensor
decreases and the voltage monitored by the module
decreases. The module uses this monitored voltage
reading to an indication of the evaporator tempera-
ture. The heater-A/C control module is programmed
to respond to this input by sending electronic mes-
sages to the Powertrain Control Module (PCM) over
the Programmable Communications Interface (PCI)
data bus, and the PCM then cycles the air condition-
ing compressor clutch as necessary to optimize air
conditioning system performance and to protect the
system from evaporator freezing. The external loca-
tion of the sensor and the use of a screw allows the
sensor to be removed or installed from the expansion
valve without disturbing the refrigerant in the sys-
tem. The evaporator temperature sensor is diagnosed
using a DRBIIItscan tool. Refer to the appropriate
diagnostic information.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the air cleaner housing from the right
side of the engine compartment.
(3) Remove the windshield wiper assembly from
the vehicle(Refer to 8 - ELECTRICAL/WIPERS/
WASHERS/WIPER MODULE - REMOVAL).
(4) Remove the temperature sensor attaching
screw from the expansion valve.
(5) Pull the evaporator temperature sensor away
from the expansion valve far enough to access the
red release ring on the wiring connector. Push the
red ring toward the connector to release lock and
remove the HVAC wire harness connector from the
temperature sensor.
(6) Remove the evaporator temperature sensor
from the engine compartment. Please note that any
grease removed with the old temperature sensor
must be replaced, failure to do so could result in poor
a/c performance.
INSTALLATION
(1) Position the evaporator temperature sensor
into the right rear corner of the engine compartment.
Please make sure any grease removed with the old
sensor has been replaced before the new sensor is
installed, failure to do so could lead to poor a/c per-
formance.
(2) Reconnect the HVAC wire harness connector
for the evaporator temperature sensor to the sensor
connector receptacle.
(3) Position the evaporator temperature sensor
onto the top of the expansion valve with the sensor
probe inserted into the well in the expansion valve.
(4) Install the temperature sensor retaining screw
and tighten.
(5) Install the window wiper assembly to the vehi-
cle(Refer to 8 - ELECTRICAL/WIPERS/WASHERS/
WIPER MODULE - INSTALLATION).
(6) Reinstall the air cleaner housing into the right
side of the engine compartment.
(7) Reconnect the battery negative cable.
(8) Run the HVAC Cool Down test to verify system
is operating properly(Refer to 24 - HEATING & AIR
CONDITIONING - DIAGNOSIS AND TESTING).

DESCRIPTION
The EGR system consists of (Fig. 1):
²EGR valve
²EGR tube
²Vacuum hoses
²EGR cooler
²EGR solenoid
OPERATION
The engines use Exhaust Gas Recirculation (EGR)
systems. The EGR system reduces oxides of nitrogen
(NOx) in engine exhaust and helps prevent detona-
tion (engine knock). Under normal operating condi-
tions, engine cylinder temperature can reach more
than 3000ÉF. Formation of NOx increases proportion-
ally with combustion temperature. To reduce the
emission of these oxides, the cylinder temperature
must be lowered. The system allows a predetermined
amount of hot exhaust gas to recirculate and dilute
the incoming air/fuel mixture. The diluted air/fuel
mixture reduces peak flame temperature during com-
bustion.

(1) Remove engine cover (Refer to 9 - ENGINE -
REMOVAL).
