The issue started today when I was using the wiper/washer. They go up, but the stophalf-way down; go all the way down then half way up; all the way...

The part that is attached to the wiper motor is in the wrong location. Remove the nut or bolt that attached the wiper transmission to the motor and remove the short arm from the wiper motor. Turn the wiper motor on and then off. wait until it stops moving. Set the wiper arms to the correct "home" position. Reattach the wiper transmission arm to the wiper motor.

you need to remove the wiper arms, the black plastic cowl- It's in 2 parts. there is also a weatherstrip that has push pins holding it and the front of the cowl. Once you get those off you will see the wiper transmission it is held in with a couple 10mm bolts. once the assembly is removed you can then see the wiper motor. Just remember once you change it over you need to time the motor if done wrong the wiper blades will just go down instead of going across the windshield.

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.

If they do not always stop in exactly the same position the live wire that feeds the park circuit in the motor has come off or the contact disc on the fibre gear in the motor has come loose.

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.

Check your wiper fuse or bad wiper motor .

It sounds like the the circuit board has gone bad and does not know where the base is any more so it will stop at the middle or the windshield. Auto Zone should have a new board if it's replaceable like the GM products. Good luck and hope this helps, In the mean time you can always turn your wipers on and pull the fuse out when it's at the down position so it's not up.

Check that you have connected the wiper motor correctly - ensure that you havent inadvertently got the polarity wrong!.
Leave the wiper arms off until you get the motor to run and park using the normal wiper on/off switch.
The motor 'park' control switching is normally an integral part of the motor drive gear and is not adjustable.
During your testing, affix a temporary indicator pointer to the end of a wiper arm drive shaft (use masking tape or similar) to prevent damage to motor or levers.
