Operation CHARM: Car repair manuals for everyone.

General Operation

In addition to standard wiper/washer system features, the Rainsense system automatically operates the wipers when rain is sensed on the windshield. This system operates only when the wiper/washer switch is in one of the AUTO DELAY positions. The speed and the duration of wiping is controlled by the Rainsense module and the wiper motor cover. The Rainsense module, which is adhered to the windshield, which is adhered to the rear-view mirror, senses the amount of rain immediately in front of it on the windshield.

The wiper motor is protected by a circuit breaker. It the wipers are blocked (by snow or ice, for example), the circuit breaker will open the circuit. The circuit breaker resets automatically when it cools.
