Wiper and Washer Systems: Description and Operation

Wipers and Washers

COMPONENT LOCATION









INTRODUCTION
The wipers have two speed controls, low and high, and an intermittent wipe mode. The wipers will park automatically irrespective of their position, when the ignition is in power mode 3 (OFF) or the control switch is selected.
A timed jet function eliminates the trail of washer fluid left on the windshield after a wiping action and reduces fluid consumption by only operating the washer jets on the up stoke of the wiper arms.
Within the wiper and washer system the following features can be attained:
- Adjustable interval intermittent wiping
- Speed dependant wiping
- Programmable wash and wipe sequencing
- Automatic moisture sensitive wiping (rain sensor).
Moisture sensitive wiping will be initiated when the vehicle is running and not in the PARK or NEUTRAL gear selection. The wiper switch must be in the AUTO position.
The system and features are controlled by the Central Junction Box (CJB).
