Wiper and Washer Systems: Description and Operation

INTRODUCTION
Windshield wiper and washer systems are standard factory-installed equipment on this model.

Windshield Wiper System
An intermittent windshield wiper system is standard equipment on this model. The intermittent wiper system lets the driver select from either of two wiper speeds, low or high, or the intermittent wipe delay mode. A knob on the end of the multi-function switch stalk is rotated to select the desired wiper speed, or the intermittent wipe delay mode and interval.

Two different versions of the intermittent wipe system are used on this model. On models that are not equipped with the optional Vehicle Theft Security System (VTSS), a conventional electronic intermittent wipe module is used that provides intermittent wipe mode delay times that are driver adjustable from about one-half second to about fourteen seconds.

On models equipped with the optional VTSS, a Central Timer Module (CTM) that contains intermittent wipe delay logic and relay control circuitry, and an external intermittent wipe relay are used to provide intermittent wipe mode delay times that are speed sensitive. Above about sixteen kilometers-per hour (ten miles-per-hour) the delay is driver adjustable from about one-half second to about eighteen seconds. Below about sixteen kilometers-per-hour (ten miles-per-hour) the CTM doubles the delay time, or provides delays of about one second to about thirty-six seconds.

The windshield wipers will operate only when the ignition switch is in the Accessory or On positions. A fuse located in the junction block protects the circuitry of the windshield wiper system.

Refer to the owner's manual in the vehicle glove box for more information on the features, use and operation of the windshield wiper system.

Windshield Washer System
An electrically operated windshield washer system is standard equipment. A paddle near the end of the multi-function switch stalk is rotated toward the instrument panel to activate the washer system. A washer reservoir in the engine compartment holds the washer fluid, which is pressurized by a pump when the windshield washer switch is actuated. The windshield washer pump feeds the pressurized washer fluid through the washer system plumbing to the windshield washer nozzles.

A standard equipment low washer fluid warning lamp in the instrument cluster will warn the driver when the washer fluid level needs to be checked. Refer to Low Washer Fluid Warning Lamp in Instrument Panel Systems for more information on this feature.

The windshield washers will operate only when the ignition switch is in the Accessory or On positions. A fuse located in the junction block protects the circuitry of the washer system.

Refer to the owner's manual in the vehicle glove box for more information on the features, use and operation of the windshield washer system.
