Sunlight Photo Sensor
Sunlight Photo Sensor
‹› There are different versions of the Sunlight Photo Sensor (G107). Make sure the allocation is correct. If a Sunlight Photo Sensor ( G107) is
installed that is not intended for that vehicle (there is a different signal than the one intended in that Climatronic Control Module (J255) A/C
control head), the Climatronic Control Module (J255) A/C control head cannot evaluate the signal from the Sunlight Photo Sensor (G107) and the
A/C system is not regulated correctly.
‹› On vehicles with heating (without A/C system), there is no Sunlight Photo Sensor (G107) installed. A cover cap is installed on these vehicles
instead.
