TWO-SPEED WIPER MOTOR-CJ MODELS
GeneralThe wiper motor is protectedby a 10-ampfuse in the
fusepanel.When the wiper switch is moved to the low speed
position,currentflows from the fusepanelto terminal Bfig. 17-13of thewiperswitch, throughthe wiperswitchto terminal 2, then throughthe green wire to the motorlow-speedbrushandthrough the armatureto ground.
With the wiper switch in the high speed position,current flows from the fuse panel to terminal B of thewiper switch, through the wiper switch to terminal 3,then throughthe redwire to the motorhigh speedbrushandthroughthe armatureto ground.
When the wiper switch is turned off, current flowsfrom the fuse panel to terminal B of the wiper switch,through the wiper switch to terminal 1, then throughthe black wire to the park contactpoints to the motor
low speedbrush and through the armatureto ground.When the cam on the wiper drive gear opens the parkcontact points, the feed circuit to the motor low speedbrush is interruptedandthe motor is in park.
TWO-SPEED WIPER MOTOR-CHEROKEE-WAGONEERTRUCK
GeneralThe wiper motor is protectedby a 10-ampfuse in the
fuse panel. Whenthe dash switch is moved to the low-speedposition, the circuit betweenterminalsA andF onthe motor are connectedand G ground through theswitch. Currentfrom the batteryflows through aseriesfield coil and is divided. One part passesthrough theshunt field coil to ground at the dashswitch; the otherpart passesthrough the armatureto groundat the dashswitch.
Moving the dash switch to the high-speedpositionopens the shunt field circuit to ground at the dashswitch andkeepsthe armaturecircuit closedto ground.The shunt field current must then pass through a 20-ohm resistor locatedon the back of the wiper terminalboard and then through terminal A that connectsthearmaturecircuit to G groundthroughthedashswitch.
Moving the dash switch to the OFF position opensboth the armatureandshuntfield circuits to groundatthe dashswitch. However,bothof thesecircuits arestillclosedto ground throughthe parkingswitch. Whenthecam on the wiper output gear opens the park switchcontacts, the ground circuit is broken and the wiperbladesare in the parkedposition.
NOTE: The shuntfield is connecteddirectly to groundbypassingthe resistorwith the switchin the off position. ThisiesvIts in low speedoperationduring the parkoperation.
Troubleshooting Procedures-CJ ModelsThe wiper motor may be operatedindependentlyof
the switch to aid in determiningdefectivecomponents.
NOTE: The wiper motormustbe groundedfor properoperationand during all wiper tests.

With ignition switch on, check for 12 volts at switchterminal 5 fig. 17-14. If 12-volt test lamp lights butwiper motor does not operate,connecta jumper wirefrom ground strapon motor to a good body ground.Ifmotor still does not operate, disconnectwiring fromswitch. Usingajumperwire, connectswitchterminals2and 5. This connectionshould give low speedoperation.If wiper motor doesnot operatein low speed,thereis anopen in the greenwire, a defectiveinternal motor connectionor a stuck low speedbrush.
To obtain high speed,connectajumperwire betweenterminals3 and5. If wiper motor fails to operate,thereis an open in the red wire, a defectiveinternal motorconnection,or a stuckhigh speedbrush.
With the wiper bladesin a position other thanpark,connecta jumperwire betweenterminals1 and 5. Thewiper bladesshould run on low speedand stop in thepark position. If, after making the jumperconnection,the motor does not run, there is an open in the blackwire, a defective internal motor connection, a misaligned or damagedsetof contactpoints or a badconnection through the park point set to the low speedbrush. If the wiper motor runsbut does not park, thecam on the drive gearis not sufficiently breakingthecontactpoints.
If wiper motor operation is intermittent,a defectivesolderjoint, wiring connection, body ground or wornbrushmaycausethe condition.
Troubleshooting Procadure-Cherokee-Wagoneer-TruckFigure 17-14 illustrates the method of connecting
leadsto the two-speedwiper either for benchoperationor to run wiper independentlyof dashswitch andvehiclewiring wheninstalledin vehicle.
Typical wiper troublesare as follows: wiper inoperative; wiper will not shutoff; wiper operatesonly on fastspeed;wiper shuts off with dash switch in high-speedposition; blades do not return to park position whenwiper is turnedOFF; wiper speednormalat low but toofast in high; intermittentoperationduringnormal wiping cycle.
Troubleshootingproceduresaredivided into two categories: wiper troubleshootingin vehicle; wiper troubleshootingon bench.

With ignition switch on, check for 12 volts at harnessterminal that connectsto wiper terminal. To dietermineif dashswitch or wiring is at fault, disconnectharnessfrom wiper motor andtry operatingwiper as shown infigure 17-14.If wiper fails to operate,removebodypartsas required,disconnecttransmissionsfrom wiper crankarm, and recheckwiper motoroperation.If wiper motorstill fails to performcorrectly, removewiper motorfromvehicle and check wiper motor accordingto procedureunderTroubleshootingon Bench.
If wiper motor will not shut off, determineif wipermotor has both low and high speeds,slow speedonly orhigh speedonly. It is importantthat the wiper operatesat low speed during parking cycle. High speed motormomentummay carry cam past normal park position,allowing parkcontactpoints to close.
Disconnectwiring harnessfrom wiper motor and tryoperatingwiper independentlyof dashswitch as shownin figure 17-14.
If wiper shuts off correctly with crank arm in parkposition and wiper has both speedsafter performing

tests,checkthe leadbetweenterminal1 anddashswitchground., and check for defectivedash switch. If wipershutsoff correctly but wiper haslow speedonly, checklead betweenwiper terminal 3 and dashswitch groundand check for defectivedash switch. If wiper shutsoffcorrectly but has high speedonly, check lead betweenwiper terminal 1 and dash switch for open circuit andcheck for defective dash switch. If wiper still fails tooperatecorrectly, remove it from vehicle and check itaccordingto instructionsunderWiper Troubleshootingon bench.
If wiper hasslow speedonly and shutsoff with dashswitch in high-speedposition,reverseharnessleadsthatconnectto wiper terminals 1 and 3 fig. 17-14.
If bladesdo not return to park positionwhenwiper isturned off, check wiper ground strap connectionto vehicle body. Remove wiper from vehicle and check fordirty, bent,or brokenparkswitch contacts.
If wiper speedis normal in low, but too excessiveinhigh speed,removewiper motor from vehicleandcheckfor an defectiveresistor.
If wiper motor operateserratically, check for loosewiper motor ground strap connection or loose dashswitch mounting.

peres,check feed wire circuit shown in figure 17-14 foropen circuit.
The low speedamp draw with no load should be 4amps; high speedamp draw 3.5 amps; motor stalledcold 12 amps.
If wiper motor is inoperative,connectwiper motor tooperatein low speedand observecurrent draw. If thereadingis zero amps,checkfor loose solder connectionat feed terminal or loose splicejoints. If readingis 1 to1.5 amps,checkfor open armature,sticking brushes,orloosesplice joint. If readingis 11 amps,checkfor brokengear,seizedshaft,or some otherconditionthatwill stallthe wiper.
If wiper motor will not shut off, this condition mayexist if wiper motor has one or both speeds.If wipermotorhas both speeds,check for park switch contactsnot openingor internal wiper motor leadthat connectsto wiper terminal 1 being grounded.If wiper motor haslow speedonly, check for grounding of internal wipermotor lead that connectsto wiper terminal 3 and checkshuntfield coil for grounding. If wiper motorhas highspeedonly, checkfor openin internal wiper motor leadthat connectsto wiper terminal 3 and check for shuntfield opencircuit.
If wiper crank arm does not return to park positionwhen wiper motor is turnedoff, checkfor dirty, bent,orbrokenparkswitch contacts.
If wiper speedis normal in low, but too excessiveinhigh speed,checkfor opencircuit in the 20-ohmresistoron backof wiper terminal board.
If wiper motor operateserratically, check for stickybrushesor loosesplice joints.
If the wiper motor will not shut off or wiper crankarm fails to stop in park position whenjumper wire isremovedfrom ground 1, checkthatparkswitch contactsare opening. Also check for ground in internal motorleadthat connectsto terminal 3.
