  1. Position the sun sensor (1) to the top of the instrument panel and connect the wire harness connector (2) to the sensor.
  2. Align the tab on the sun sensor (1) with the slot in the opening in the defroster grille (2) and install the sensor onto the grille. Make sure that the sensor is fully engaged to the defroster grille.
  3. Reconnect the negative battery cable.
Sun Sensor - Removal3 steps
⚠ WARNING
Disable the airbag system before attempting any steering wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the negative battery (ground) cable. 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 airbag system. Failure to follow these instructions may result in possible serious or fatal injury.

Solar Sensor: Testing and Inspectionreference
⚠ WARNING
Disable the airbag system before attempting any steering wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the negative battery (ground) cable. 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 airbag system. Failure to follow these instructions may result in possible serious or fatal injury.
DIAGNOSIS AND TESTING - SUN SENSOR The sun sensor is located so that the sun rays will hit the sensors in the same way that it will hit the driver and the passenger. If the vehicle exhibits a lack of passenger comfort in sunny weather such as in the early afternoon, inspect the area around the sun sensor on top of the dash panel. It is important that the area of the sun sensor be unobstructed from plain view. Check for the following: -Sun sensor is properly installed Sun Sensor - Installation. -Any stickers on the windshield are not directly in front of the sun sensor. -Any items laying on top of the instrument panel are not covering the sun sensor. -Windshield wipers are properly adjusted. The A/C-heater control continually monitors the sun sensor circuits and will store Diagnostic Trouble Codes (DTCs) for any problem it detects. The sun sensor can be tested in the vehicle with a scan tool Testing and Inspection.
Infrared Temperature Sensor - Descriptionreference
Fig. 1
Fig. 1
DESCRIPTION The infrared temperature sensor (1) consists of an infrared transducer concealed behind a clear lens (4) located in a molded plastic housing with an integral wire connector receptacle (2) and mounting and alignment tabs (3 and 5). The infrared sensor is used only on models equipped with the automatic temperature control (ATC) heating-A/C system.
Sun Sensor - Descriptionreference
ℹ NOTE
Typical sun sensor assembly shown.
Fig. 1
Fig. 1
DESCRIPTION The Automatic Temperature Control (ATC) heating-A/C system uses a sun sensor (1) to measure sun light intensity. The sun sensor incorporates two sun load sensors (2) within a molded plastic case which is mounted to the instrument panel and a clear lens (3) that protrudes through the defroster grille. The wire harness receptacle (4) connects the sun sensor to the vehicle electrical system.
