Refer to Group 8W - Wiring Dia-grams for complete circuit descriptions and diagrams.WINDSHIELD WIPER SYSTEM An intermittent wiper system is standard equip-ment on all Grand Cherokee models. The intermit-tent wipe system allows the driver to select from twowiper speeds or an intermittent wipe feature that al-lows a delay between wipes of 2 to 15 seconds. Referto the owner’s manual for more information on wipersystem controls and operation. The wipers will operate only when the ignitionswitch is in the ACCESSORY or ON position. A cir-cuit breaker in the fuseblock module protects the cir-cuitry of the wiper system.CAUTION: The wiper arms and blades must neverbe moved manually from side to side or damagemay result.WINDSHIELD WASHER SYSTEM • a park mode that operates the wiper until it A electrically-operated windshield washer system is reaches its park position when the liftgate wiperstandard equipment on all Grand Cherokee models. switch is turned offThe washers will operate only when the ignition • a rear washer mode that provides 2-3 wiperswitch is in the ACCESSORY or ON position.

ZJ WIPER AND WASHER SYSTEMS 8K - 5 WINDSHIELD WIPER/WASHER SYSTEM SCHEMATIC The intermittent wipe module is attached to the left cowl side panel beneath the instrument panel and behind the cowl side trim panel with a hook and loop fastener patch. The following tests are to be performed if a prob- lem with wiper system is only evident in the DELAY mode. These tests involve disconnecting the intermit- tent wipe module.

PROCEDURE Variations in delay should be as follows: (1) Minimum delay (delay control to extreme coun- terclockwise position before first detent) 1/2 to 2 sec- onds. (2) Maximum delay (delay control to extreme clock- wise position before off detent) 10 to 30 seconds.
