GENERAL INFORMATION

Following are general descriptions of the major

components in the Dakota wiper and washer sys-

tems. Refer to Group 8W - Wiri ng Diagrams for com-

plete circuit descriptions and diagrams.

WINDSHIELD WIPER SYSTEM

An intermittent wiper system is standard equip-ment on all Dakota models. This system allows the

driver to select from two wiper speeds or an intermit-

tent wipe feature that allows a delay between wipes

of 2 to 15 seconds. Refer to the owners manual for

more information on wiper system controls and oper-

ation.

The wipers will operate only when the ignition

switch is in the ACCESSORY or ON position. F use

10 in the fuseblock module protects the circuitry ofthe wiper system.

WINDSHIELD WASHER SYSTEM

A electrically-operated windshield washer system isstandard equipment on all Dakota models. The wash-ers will operate only when the ignition switch is inthe ACCESSORY or ON position. Fuse 10 i n thefuseblock module protects the circuitry of the washersystem. Refer to the owners manual for more infor-mation on washer system controls and operati on.

WIPER ARMS, BLADES, AND ELEMENTS

All Dakota models have two 18-inch wiper bladeswith replaceable rubber elements (squeegees). Bladesare supplied by two manufacturers and are inter-changeable as assemblies. However, replacement

squeegees are not interchangeable between bladetypes.

Caution should be exercised to protect the rubbersqueegees from any petroleum-based cleaners or con-taminants, which will rapidly deteriorate the squee-gee rubber. If squeegees are damaged, worn orcontaminated they must be replaced.

Wiper squeegees exposed to the weather for a longtime tend to l ose their wiping effectiveness. Periodiccleaning of the squeegees is suggested to remove de-posits of salt and road film. The wiper blades, armsand windshield should be cleaned with a sponge or

cloth and a mild detergent or non-abrasive cleaner. I f

the squeegees continue to streak or smear, they

should be replaced.

The blades are mounted to two spring-loaded wiper

arms. Spring tension of the wiper arms controls the

pressure applied to the blades on the windshield. The

wiper arms are attached by an integral latch to thetwo wiper pivots on the cowl grille panel at the base

of the windshield. The wiper arms and blades can

not be adjusted or repaired. I f faulty, they must be

replaced.

WIPER LINKAGE AND PIVOTS

The wiper pivots are fastened to the cowl top panel

with screws beneath the cowl cover/grille panel. Each

pivot assembly can be replaced by removing the cowl

grille panel, unsnapping the linkage bushing(s) from

the pivot crank arm pins, and removing the mount-

ing screws.

The two pivot cranks are joined by a connectinglink, and a drive link connects the motor crank to the

drive link near the left pivot. Pr essed-in plastic bush-

ings in the ends of the links can be replaced if worn

or damaged.

WIPER MOTOR

The two-speed permanent magnet wiper motor has

an integral transmission and park switch. The motor

is mounted to the engine side of the cowl panel with

a reinforcement/stud plate and a rubber-isolated

mounting bracket. The wiper motor output shaft

passes through the cowl panel into the cowl plenumarea, where a crank arm attached to the output shaft

drives the wiper drive link.

Wiper speed is controlled by current flow to the ap-

propriate set of brushes. The wiper motor completes

its wipe cycle when the switch is turned OFF, and

parks the blades in the lowest portion of the wipe

pattern. The wiper motor assembly can not be re-

paired. I f faulty, the entire motor assembly must be

replaced. The crank arm, mounting bracket, and r e-

inforcement/stud plate are available for service.

WIPER/WASHER SWITCH

Controls for the windshield wiper and washer sys-tems are contained in the multi-function switch con-trol lever. The multi-function switch is mounted onthe left side of the steering column between thesteering wheel and the instrument panel. This switchalso controls many other functions. The multi-func-

tion switch can not be repaired. I f any function of theswitch is faulty, the entire switch must be replaced.

INTERMITTENT WIPE MODULE

I n addition to low and high speed, the intermittentwipe system has a delay mode. The delay mode has arange of 2 to 15 seconds. The length of the delay isselected with a variable resistor in the wiper switchand is accomplished by electronic circuitry within theintermittent wipe module. I f the washer knob is de-pressed while the wiper switch is in the OFF posi-tion, the intermittent wipe module will operate thewiper motor for approximately 2 wipes and automat-

ically turn the motor off. The intermittent wipe mod-ule is mounted to the instrument panel, behind theknee blocker and to the right of the steering column.The module can not be repaired.

WASHER NOZZLES

The two fluidic washer nozzles are snap-fit intoopenings in the cowl grille panel below the wind-shield and are not adjustable. Washer fluid is fed tothe nozzles through hoses clipped to the underside ofthe cowl grille panel. T he nozzles can not be repairedand, if faulty, should be replaced.

WASHER RESERVOIR

The washer solvent reservoir is mounted to the leftfront inner fender shield near the cowl panel. I t hasa provision for a l ow washer flui d l evel sensor. Referto Group 8E - I nstrument Panel and Gauges for di-agnosis and service of the sensor. The reservoir andfil ler cap are available for service.

WASHER PUMP

The washer pump and motor are press-fit into arubber grommet near the bottom of the washer res-ervoir. A permanently lubricated and sealed motor is

coupled to a rotor-type pump. Washer fluid is gravityfed from the reservoir to the pump. The pump thenpressurizes the fluid and forces it through the plumb-ing to the nozzles when the motor is energized. Thepump and motor can not be repaired. I f faulty, theentire assembly must be replaced.

DIAGNOSIS

WIPER MOTOR

The following are wiper motor system problems,

tests to be performed to locate the faulty part, and

the proper action to be taken. I f the malfunction in-

volves only the delay mode, switch, or wiring, see the

diagnosis for I ntermittent Wipe Module and Wiper/Washer Switch.

CONDITION

Motor will not run in any wiper/washer

switch position.

PROCEDURE

(1) Check fuse 10 in the fuseblock module. I f OK ,go to step 3. I f not OK, replace fuse and go to nextstep.

(2) Check motor operation in all wiper/washerswitch positions. I f not OK and fuse blows, go to step5. I f not OK and fuse is OK , go to next step.

(3) Pl ace wiper/washer switch in L OW position andlisten to motor. I f you cannot hear it running, go tonext step. I f motor is running, check motor outputshaft. I f output shaft is not turning, replace motorassembly. I f it is turning, drive link to output shaftor linkage is not properly connected. Replace wornparts and/or properly connect drive link to the motoroutput shaft.

(4) Connect a voltmeter between motor terminal Land ground strap (Fig. 1). If there is little or no volt-age (less than 1 volt), move negative test lead from

the ground strap to battery negative terminal. I f anincrease in voltage is noticed, the problem is a badground circuit. Make sure the motor mounting is freeof paint and that mounting fasteners are tight. I fthere is still no indication of voltage, the problem i san open in wiring or faulty wiper/washer switch. If asmall increase (greater than 3 volts) in voltage is ob-served, the problem i s a faulty motor assembly.

(5) Disconnect motor wiring connector and replace

fuse. I f fuse does not blow, motor is defective. I f fuse

blows, wiper/washer switch or wiring is at fault.

CONDITION

Motor runs slowly at all speeds.

PROCEDURE

(1) Disconnect wiring harness connector at motor.

Remove wiper arms and blades. Connect an ammeter

between battery and terminal L on motor (Fig. 2). I f

motor runs and average ammeter reading is more

than 6 amps, continue to next step. I f motor runs

and average ammeter r eading is less than 6 amps, go

to step 3.

(2) Check wiper linkage or pivots for binding or ob-

struction. Di sconnect drive link from motor. I f motor

now runs and draws less than 3 amps, repair linkage

system. I f motor continues to draw more than 3

amps, r eplace motor assembly.

(3) Check motor wiring harness for short between

high and l ow speed circuits. Connect a voltmeter or

test lamp to motor ground strap. Set wiper/washer

switch to L OW position. Connect other lead of volt-

meter (test lamp) to terminal H of the wiring har-

ness. I f voltage is present, there is a short in the

wiring or wiper/washer switch. I f no voltage is

present, go to next step.

(4) Set wiper/washer switch to HI GH position.

Move voltmeter (test lamp) l ead from terminal H to

terminal L of the wiring harness. If voltage is

present, there is a short in the wiring or wiper/

washer switch.

CONDITION

Motor will run at high speed, but not at low

speed.

Motor will run at low speed, but not at high speed.Fig. 1 Voltmeter Between Terminal L and Ground

PROCEDURE

(1) I f motor will not run on high speed, put wiper/washer switch in H I GH position. Connect a test lampbetween motor terminal H and ground (F ig. 3). I f mo-tor will not run on low speed, put wiper/washerswitch in L OW position. Connect a test lamp betweenmotor terminal L and ground.

(2) I f test lamp does not light at motor terminal,there i s an open in wiring or wiper/washer switch. I ftest lamp lights at motor terminal, replace motor as-sembly.

CONDITION

Motor will keep running with wiper/washerswitch in OFF position.

PROCEDURE

(1) Disconnect wiring harness connector at motor.Connect jumper from terminal P2 to terminal L ofwiper motor (F ig. 4).

(2) Connect second jumper from terminal P1 tobattery. I f motor runs to park position and stops,wiper/washer switch is faulty. I f motor keeps runningand does not park, replace motor assembly.

CONDITION

Motor will stop wherever it is, when wiper/washer switch is put in OFF position. (Wipersdo not continue running to park position.)

PROCEDURE

(1) Remove motor wiring connector and clean ter-minals. Reconnect connector and test motor. I f notOK, go to step 2.

(2) Put wiper/washer switch in OFF position. Dis-connect motor wiring connector. Connect a voltmeteror test lamp to the motor ground strap. Connect theother lead to terminal P1 of wiring connector. I f volt-age is not present, check for an open circuit in thewiring harness or wiper/washer switch. I f voltage is

present, go to next step.(3) Connect an ohmmeter or continuity tester be-tween terminals L and P2 (Fig. 5). I f there is conti-nuity between these terminals, the problem is adefective motor. I f there is no continuity, the problemis an open in wiring or a faulty wiper/washer switch.

WIPER/WASHER SWITCH

Use an ohmmeter to test for continuity (no resis-

tance) between the terminals of the switch as shown

in the Multi -Function Switch Continuity chart (Fig.

6).

INTERMITTENT WIPE MODULE

See Wiper Motor or Wiper/Washer Switch for diag-

nosis of system problems which do not involve the

DEL AY function. I f problem occurs only in the DE-L AY mode, the following tests are to be performed.

These tests involve disconnecting the intermittent

wipe module, which can be found on a bracket lo-

cated behind the knee blocker (Fi g. 7).

CONDITION

Excessive delay (more than 30 seconds) or in-

adequate variation in delay.

PROCEDURE

Variations in delay should be as follows:(1) Minimum delay (wiper/washer switch to ex-

treme counter-clockwise position before L OW detent)1/2 to 2 seconds.

(2) M aximum delay (wiper/washer switch to ex-treme clockwise position before OF F detent) 10 to 30seconds.

(3) I f there is excessive delay or no variations indelay, see Wiper/Washer Switch.

CONDITION

In DELAY mode wipers run continually whenwash is operated, but do not provide an extrawipe when the washer switch is released.

PROCEDURE

Replace the intermittent wipe module.

CONDITION

Wipers start erratically during DELAY mode.

PROCEDURE

(1) Verify that the ground connection at the instru-ment panel is making good connection (free frompaint) and is tight.

(2) Verify that the motor ground strap is makinggood contact and that the motor mounting bolts are

tight.(3) Verify that the wiring ground connections forthe intermittent wipe module and the wiper/washerswitch are tight.

(4) I f condition is not corrected, replace intermit-tent wipe module.

WASHER PUMP

(1) Check for continuity between black wire ofpump connector and a good ground. There should becontinuity. I f OK, go to next step. I f not OK , repairground circuit as required.

(2) Turn ignition switch to ON position. Check for

battery voltage at brown wire of pump connectorwith washer switch depressed. I f OK , replace pump.I f not OK , see diagnosis for Wiper/Washer Switch inthis group. I f switch tests OK , repair wiring betweenswitch and pump as required.
