Windshield wipers intermittent on 2002 Windstar

Question edited for clarity.
Question moved to category.

The thing that leaps off your question is that windshield *wipers* don't have hoses. It is an electric motor and two articulated arms.

For replacing *washer* hoses, you just buy a length of hose and cut it, or you can buy ready made with nozzles.

There should be a printed circuit board on the motor that controls the intermittent and park functions of the wipers.

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.

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

?€¢
Instrument panel cluster (IPC)

?€¢
ACC 15-amp fuse

?€¢
WSW 30-amp fuse

Your problem is probably in the wiper transmission itself. There is a switch that tells what position to stop feeding power to the motor. But if that switch isn't working, the rest of the system does not know what to do, nor exactly when! However, if you have a good concept of timing, what you COULD do, is simply turn the wiper switch off the instant they are at the "lowest point" in their sweep cycle ... at a cost of NOTHING!

Hey Anon,
I just finished replacing the intermittent (wiper motor pulse board) control on my vehicle.. it was doing exactly as you describe.. it wasn't hard.. just time consuming..

check to see if you have a good ground at the wiper motor if so the wiper motor will need to be replaced

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.

If you have just changed the wiper arms, they may not have been reinstalled correctly.....hoever if it has just started happening,,,,,???

unfortunately this is a wiper motor fault....not the switch.......inside the motor is a PARK function.....this is where the wipers will stop after doing a swipe across the windscreen and the switch is turned off.........this park function is a section inside the motor that cannot be removed and replaced internally, and it would cost more than just a replacement wiper motor

Good luck and i hope this helps...

switch or motor, not trans.

The wiper blades are probably generics, or your technician put the wrong blades on. (most likely generics). I would reccommend going to a Pontiac dealership and getting factory blades. OEM parts are highly reliable.
