Wipers Inoperative -One or More Modes (Front Wipers)
Diagnostic Aids
The Wash mode for this diagnostic procedure is defined as the mode when the wiper switch is OFF and only the windshield washer switch has been activated. When the washer switch is activated with the wiper switch OFF, the wipers should wipe the windshield 3-5 times and then park.
Test Description
The number below refer to the step numbers on the diagnostic table.
- This step will pinpoint which speci?c wiper functions are inoperative. The wipers should operate for all active windshield wiper switch positions. When the wiper switch is OFF and only the windshield washer switch is activated, the wipers should wipe the windshield 3-5 times and then park.
- This step will help to pinpoint which speci?c circuit or component may be involved in the malfunction. When the Wash, and Park modes are inoperative as well as the Intermittent mode, the windshield wiper switch mist/off/low signal circuit and associated components are suspect. When the wipers operate for the Park mode but the Intermittent and Wash modes are both inoperative, suspect the accessory voltage feed circuit of the FRT WIPER Relay or an associated component.
- This step is used when the wipers fail to wipe the windshield while only the washer switch is activated.
- This step is used when the wipers still operate in all wiping modes, but fail to Park at the full down position. If this condition is present while the wipers are being operated in the Intermittent mode, the wipers typically will not return to the full down position. Instead, they will stop at random positions on the windshield and in between the timed wiper strokes. Or, if the wipers are being operated in either the High or Low mode, the wipers will stop in mid-stroke when the wiper switch is turned OFF.

Wipers Inoperative -One or More Modes (Rear Wipers)
Diagnostic Aids
Except for when it is in the Wash mode, the rear window wiper wipes the rear window at delay time intervals. With the rear wiper system activated, the length of time between wipes can be adjusted by selecting any one of the three delay speed settings of the windshield wiper switch.
During the Wash mode, if the rear washer switch is momentarily turned to ON, the rear wiper will wipe the rear window 3-5 times and then park. However, if the rear washer switch is held to ON, the rear window wipers will continue to operate until the switch is released.
While the delay speed of both the front and rear wipers is adjusted by the windshield wiper switch selections, the delay time intervals of the rear wiper are not synchronized with the delay time intervals of the front wipers.
The rear wiper should stop at the Park position anytime the rear wiper is not wiping. However, if the ignition switch is turned OFF while the rear wiper is wiping, the wiper will stop at its current location on the glass.
Test Description
The numbers below refer to the step numbers on the diagnostic table.
- This step will determine if the rear wiper operates properly when only the rear window washer switch is activated. When the rear window washer switch is operated with the rear wiper switch OFF, the rear wiper should wipe the window 3- 5 times and then park.
- This step helps to pinpoint the specific malfunction. The Park mode of the rear window wiper may be the only feature malfunctioning. When the rear wiper switch is ON, the rear wiper should stop at the parked position in between the timed strokes of the wiper. When the rear wiper switch is turned OFF, the rear wiper should park and remain in the parked position until either the wipe or wash mode is operated again.

GENERAL DESCRIPTION AND SYSTEM OPERATION
Windshield Wiper System
The windshield wiper system consists of a wiper motor, a linkage, a wiper arm, a blade and a wiper/washer switch. The windshield wiper circuit incorporates a selfparking device which consists of a worm gear and a cam plate in order to keep the circuit engaged temporarily when the switch is turned off. The wiper system is driven by a permanent magnet-type motor. The windshield wiper motor is mounted on the dash panel and is directly connected to the windshield wiper linkage.
The windshield wiper motor has two speeds, LO and HI, and also has intermittent wiper capability. The wiper switch is an integral part of the wiper/washer switch. Windshield wiper operation is actuated through the lever on the right side of the steering column.
Windshield Washer System
The windshield washer system is equipped with a washer fluid reservoir, a washer fluid pump, hoses, nozzles, and a wiper/washer switch. The windshield washer reservoir is mounted behind the front right wheel well splash shield. Attached to the reservoir is a washer pump, which pumps fluid through the hoses to the two nozzles mounted on the hood. The washer switch is an integral part of the wiper/washer switch. Windshield washer operation is actuated through the lever on the right side of the steering column.
