The dual light and rain sensor "a" transmits information about the outside light and determines the amount of water on the windshield. The sensor also transmits infrared radiation information, which is necessary for the climate control system. The sensor is located inside the passenger compartment and is glued to the windshield. The system operates regardless of the color of the windshield.
Replacing the windshield with the same one does not affect the operation of the system and does not lead to deterioration of its characteristics.
