Chrysler Sebring, Stratus sedan, Sebring Convertible. Manual - part 734
INSTALLATION
(1) Install the recirculation door actuator onto the
HVAC air inlet housing. If necessary, rotate the
actuator slightly to align the splines on the actuator
output shaft with those on the actuator gear (Fig.
46).
(2) Install the three screws that secure the recircu-
lation door actuator to the HVAC air inlet housing.
Tighten the screws to 2 N·m (17 in. lbs.).
(3) Connect the wire harness connector to the
recirculation door actuator.
(4) Install the instrument panel (Refer to 23 -
BODY/INSTRUMENT
PANEL/INSTRUMENT
PANEL ASSEMBLY - INSTALLATION).
(5) Reconnect the negative battery cable.
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.
