SUN SENSOR
DESCRIPTION
The sun sensor (Fig. 47) is used on vehicles
equipped with the automatic temperature control
(ATC) system only. The sun sensor is mounted below
the instrument panel top cover.
OPERATION
The sun sensor is not a thermistor type sensor, but
rather a photo diode. For this reason the sun sensor
responds to sun light intensity rather than tempera-
ture. The sun sensor is used to aid in determining
proper mode and blend door positions and blower
motor speed. The sun sensor is also used to sense
day and night conditions for automatic headlight con-
trol, if equipped. The sun sensor has an LED indica-
tor for the vehicle security system, if equipped.
The sun sensor is diagnosed using the DRBIII
t
scan tool. Refer to Body Diagnostic Procedures.
The sun sensor cannot be adjusted or repaired and,
if faulty or damaged, it must be replaced.
DIAGNOSIS AND TESTING
SUN SENSOR
WARNING: On vehicles equipped with airbags, dis-
able the airbag system before attempting any steer-
ing 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. This is the only sure way to disable the air-
bag system. Failure to take the proper precautions
could result in an accidental airbag deployment and
possible personal injury or death.
The sun sensor assembly is located so that the sun
rays will hit the sensors in the same way that it will
hit the driver and the passenger. It is important that
the area in front of the sun sensor assembly be unob-
structed. Check for the following:
• Windshield wipers are properly adjusted.
• Instrument panel top cover or sun sensor is
properly installed. The sun sensor should be 6 mm
(1/4 in.) above the top cover.
• Any stickers on the windshield are not directly
in front of the sensor.
• Any items laying on the instrument top pad are
not covering the sensor.

sun sensor after shimming, use 8-15 x 1 inch
screws, or equivalent.
(5) Reinstall the screws that secure the sun sensor.
Do not overtighten the screws.
(6) Reinstall the instrument panel top cover (Refer
to 23 - BODY/INSTRUMENT PANEL/INSTRUMENT
PANEL TOP PAD - INSTALLATION).
The sun sensor can be tested in the vehicle with
the DRBIII
t scan tool. Refer to Body Diagnostic Pro-
cedures manual for further information.

THERMAL LIMITER SWITCH
DESCRIPTION
A thermal limiter switch is used on A/C compressor
in vehicles equipped with the 2.0L engine and the
2.4L Turbo engine. The thermal limiter switch mea-
sures A/C compressor surface temperature. If the
compressor surface temperature rises above a prede-
termined range, the thermal limiter switch cuts the
battery feed to the A/C clutch field coil to prevent
damage to the A/C compressor. The thermal limiter
switch will reset once the compressor temperature
returns to safe operating temperatures.
OPERATION
The thermal limiter switch interrupts battery feed
to the A/C clutch field coil when temperatures reach
above 122 - 128° C (250 - 260° F). The switch
restores clutch field coil battery feed when the tem-
perature drops to below 104 - 116° C (220 - 240° F).
The thermal limiter switch cannot be adjusted or
repaired and , if faulty or damaged, the A/C compres-
sor must be replaced
DIAGNOSIS AND TESTING
THERMAL LIMITER SWITCH - 2.0L/2.4L
ENGINES
NOTE: The thermal limiter switch is not serviceable.
If the switch fails, the A/C compressor must be
replaced.
The thermal limiter is calibrated to open and close
at the following temperatures:
• Open circuit (no continuity): 122° - 128° C (252°
- 262° F)
• Close circuit (continuity): 106° - 116° C (225° -
235° F)
Test the thermal limiter switch as follows:
(1) Disconnect the wire harness connector from the
thermal limiter switch.
(2) With
an
ohmmeter,
check
for
continuity
between the two thermal limiter switch terminals. If
no continuity is present, replace the A/C compressor
(Refer to 24 - HEATING & AIR CONDITIONING/
PLUMBING/A/C COMPRESSOR - REMOVAL).

There are two side window demister air outlets.
One located on each end of the instrument panel top
cover. The airflow from the side window demister air
outlets is directed by fixed vanes in the outlets and
cannot be adjusted. The side window demister air
outlets are only serviced with the instrument panel
top cover (Refer to 23 - BODY/INSTRUMENT PAN-
EL/INSTRUMENT PANEL END CAP - REMOVAL).
There are four instrument panel air outlets. One
air outlet is located near each outboard end of the
instrument panel facing the rear of the vehicle and
two air outlets are located above the top of the
instrument panel center bezel. The air outlet located
at the right end of the instrument panel can be
removed individually for service replacement. The
other instrument panel air outlets are part of the
instrument cluster bezel and cannot be serviced sep-
arately (Refer to 23 - BODY/INSTRUMENT PANEL/
CLUSTER BEZEL - REMOVAL).
Each of the instrument panel air outlets contain an
air outlet barrel that is used to direct or shut off the
flow of the conditioned air leaving the instrument
panel. All of the air outlet barrels can be removed
individually for service replacement.
