Sunlight Photo Sensor -G107-
Note
♦
There are different versions of the sunlight photo sensor. Make
sure the allocation is correct. Refer to the Electronic Parts
Catalog. If a sunlight photo sensor is installed that is not in‐
tended for that vehicle (there is a different signal than the one
intended in that Climatronic control module -J255- ), the Cli‐
matronic control module cannot evaluate the signal from the
sunlight photo sensor and the A/C system is not regulated
correctly.
♦
On vehicles with no A/C (heater only), there is no sunlight
photo sensor installed. A cover cap is installed on these vehi‐
cles instead.
– Switch off ignition.
– Carefully pry cover -A- out of windshield defroster vent -D-.
Refer to⇒ Body Interior; Rep. Gr. 70 ; Removal and Installa‐
tion .
Note
First carefully loosen retainers -F- from defroster vent -D- with a
small screwdriver -E-. Do not damage surface of cover -A- or de‐
froster vent -D- when doing so.
– Carefully pry sunlight photo sensor -B- out of front windshield
defroster vent -D-.
– Disconnect connector -C-.
Note
Do not interchange Sunlight Photo Sensor -G107- -B- (4 electrical
connections) with light emitting diode for central locking system
and interior monitoring system -G- (2 electrical connections).
