Sliding cam locks (6) on each side of the sensor housing (5) (either side of the connector) secures the sensor to the mounting bracket (2) which is bonded (1) to the windshield glass. A small screwdriver can be used to push in on the tabs until the slider protrudes from the opposing side of the sensor housing. Concealed within the sensor housing is the electronic circuitry of the module, which includes four infrared diodes (3), four photocells (4), and a microprocessor (7) and connector wiring (10). The electronic circuity components are held together by screws (8) and housing bezel (9).

The rain sensor software is Flash compatible, which means it can be reprogrammed using Flash reprogramming procedures. However, if any of the hardware of the sensor is damaged or faulty, the entire rain sensor module must be replaced. The rain sensor bracket is available for service replacement.
