Wiper/Washer Systems: Description
All models have a 2-speed wiper motor with intermittent wipe feature. GLC and RX7 models may be equipped with a rear window wiper/washer system. The wiper switch for GLC Wagon is a lever on the left side of the steering column.
On all other models wiper lever is on the right side of column. A time delay relay is used to control the intermittent cycle on all except RX7 models. On RX7, wipers are timed by the "Control Processing Unit" that also operates a number of other accessories.
