Windshield wiper connector

When the windshield wiper / washer switch is turned to the OFF position while the wiper motor is somewhere in mid-cycle, the wiper motor module will continue to operate the wiper motor until the wipers reach the park position. If the ignition is turned off while the wipers are in mid-cycle, the wipers will stop immediately where they are. The wipers will park the next time the ignition is cycled to the ON position.

Wiper/Washer System Components
The Wiper / Washer System consists of the following components:
• Windshield wiper / washer switch
• Windshield wiper system module / motor
• Windshield washer fluid pump
• Windshield washer fluid level switch
• WPR 25A fuse
Wiper / Washer System Operation
The windshield wiper motor module is part of the windshield wiper motor cover and controls the wiper motor operation. The windshield wiper motor is a 2 speed motor. Windshield wiper DELAY operation is a low speed wiper motor function with a variable delay interval between the wipe cycles. The DELAY interval is controlled through a series of resistors within the wiper / washer switch.
Park Position Operation
When the windshield wiper / washer switch is turned to the OFF position while the wiper motor is somewhere in mid-cycle, the wiper motor module will continue to operate the wiper motor until the wipers reach the park position. If the ignition is turned off while the wipers are in mid-cycle, the wipers will stop immediately where they are. The wipers will park the next time the ignition is cycled to the ON position.

I would make an assumption as it is the wiper motor going bad. Most any I have seen the motor runs in a constant 360 degree revolution and not back and forth. The back and forth motion comes from the linkages under the plastic cowl in front of the windshield.

Hi Jill,
The first thing to check is a 13mm nut that holds the wiper arm in place.See if you can move the wiper arm freely back and forth.There is a nut at the base of that wiper arm,Lift up a cover that is hiding the nut. If it comes loose from being froze from ice or snow. Put the wiper in its rest position and tighten the nut back up.

sounds like the connecting rod between both wiper arms either broke or one of the keepers popped off under the connector for that arm..since the wiper system IS NOT designed to wisk snow off the window once accumulated, this can an does happen.. even seen motors get burned out doing this..cleaning the window first will save this issue and the equiptment. need to acess this arm<take off the vented peice below the windshield and everything should be visible there..repost findings

The park position is controlled inside the motor/actuator assembly. Not sure if it can be repaired. See if it is assembled with screws versus rivets. A new assembly is less than $100.

Intermittent Speed Windshield Wipers
The intermittent wiper speed is activated with grounds controlled by the multifunction switch inputs to the windshield wiper motor module. The windshield wiper motor module then activates the windshield wiper RUN/PARK relay coil and switches voltage through the windshield wiper high/low relay. The high/low relay remains deactivated supplying the voltage to the wiper motor low speed input and activates the windshield wiper motor. When the windshield wiper motor module receives the grounded input, the motor continues to operate until Hall effect senses magnet to turn off RUN/PARK sense the output to the windshield wiper RUN/PARK software, deactivating the relay and disconnecting voltage to the wiper motor. The windshield wipers remain parked until the windshield wiper motor module completes a time-out and then repeats the intermittent windshield wiper cycle.

• The intermittent windshield wiper speed does not operate correctly

• Multifunction switch.
• Circuitry.
• Windshield wiper motor.

• Go To Pinpoint Test D .

Pinpoint Test D: The Intermittent Windshield Wiper Speed Does Not Operate Correctly
Normal Operation During normal operation, the windshield wiper motor receives voltage at all times through battery junction box (BJB) fuse 1 (30A), circuit 65 (DG). The windshield wiper motor also receives power with the ignition switch in RUN or ACC positions through central junction box (CJB) fuse 33 (15A), circuit 1002 (BK/PK). Ground is provided to the windshield wiper motor through circuit 676 (PK/OG) and circuit 57 (BK). The run/park and high/low relays are contained in the wiper motor electronics. Mode of operation is dependant on the signal(s) received from the multifunction switch.

Possible Causes
• Multifunction switch
• Open in circuit 57 (BK), 56 (DB/OG), 61 (YE/RD) or 63 (RD)
• Windshield wiper motor

PINPOINT TEST D: THE INTERMITTENT WINDSHIELD WIPER SPEED DOES NOT OPERATE CORRECTLY Test Step Result / Action to Take D1 CHECK THE MULTIFUNCTION SWITCH

• Key in OFF position.
• Disconnect: Multifunction Switch C202b.
• Carry out the multifunction switch component test. Refer to Wiring Diagrams Cell 149 for schematic and connector information.
  
• Did the multifunction switch pass the component test?

Yes
GO to D2 .

No
INSTALL a new multifunction switch. REFER to Section 211-05 . TEST the system for normal operation. D2 CHECK CIRCUIT 57 (BK) FOR OPEN

• Measure the resistance between multifunction switch C202b-6, circuit 57 (BK), harness side and ground.
• Is the resistance less than 5 ohms?

Yes
GO to D3 .

No
REPAIR the circuit. TEST the system for normal operation. D3 CHECK CIRCUITS 56 (DB/OG), 61 (YE/RD) AND 63 (RD) FOR OPENS

• Disconnect: Windshield Wiper Motor C125.
• Using the following table, measure the resistance between multifunction switch C202b harness side and windshield wiper motor C125 harness side:
  
  Multifunction Switch C202b Windshield Wiper Motor C125 Pin 2, circuit 56 (DB/OG) Pin 10, circuit 56 (DB/OG) Pin 4, circuit 61 (YE/RD) Pin 1, circuit 61 (YE/RD) Pin 1, circuit 63 (RD) Pin 9, circuit 63 (RD) Pin 3, circuit 58 (WH) Pin 11, circuit 58 (WH)
• Is the resistance less than 5 ohms?

Yes
GO to D4 .

No
REPAIR the circuit(s) in question. TEST the system for normal operation. D4 CHECK FOR CORRECT WIPER MOTOR OPERATION

• Disconnect all wiper motor connectors.
• Check for:
  • corrosion.
  • pushed-out pins.
• Connect all wiper motor connectors and make sure they seat correctly.
• Operate the system and verify the concern is still present.
• Is the concern still present?

Yes
GO to D5 .

No
The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. TEST the system for normal operation. D5 CHECK THE WINDSHIELD WIPER MOTOR

• Key in OFF position.
• Disconnect: Windshield Wiper Motor C125.
• Carry out the windshield wiper motor component test as outlined in this section.
• Did the windshield wiper motor pass the component test?

Yes
The system is operating correctly at this time. Concern may have been caused by incorrect binding pivot arm adjustment. REFER to Wiper Blade and Pivot Arm Adjustment in this section. TEST the system for normal operation.

No
INSTALL a new windshield wiper motor. REFER to Windshield Wiper Motor in this section.

Wiper motor rarely goes bad, and a second one going bad as well is extremely rare. What will burn out a motor is very high resistance to movement from the wiper assembly. Do the following: Take out the wiper motor, and move the wipers by hand to see if they are hard to move, or if the arms (rod mechanism) are rubbing against anything. Do this with the blades in normal position, resting against the windshield. Pour water unto windshield while testing it, to avoid scratches. One telltale sign for this condition, is the wipers going too slow before complete stoppage. Either that, or an electrical connection leading to the wiper motor, for that simply check that there is electricity in the wiper motor connector when wipers are activated.

there are no screws they are retainers that pop off / the trick is to be careful pulling off the vent cowl panels because the clips can be hard to get look what side you need to take off and their may be ends which should come off first.

The grooves on the motor shaft got worn out or something that holds the wiper shaft to the motor broke. take off the wiper shaft and you have more or less an idea what it could be.it is obviously not the motor.
