Pinpoint Test I: The Rear Wiper Wash and Wipe Function Does Not Operate (Freestyle Only): Testing

WARNING: This page is about a different car, the 2005 Mercury Montego, 2005 Ford Freestyle, and 2005 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.
  1. I1 CHECK THE LIFTGATE AJAR PID 
    • Monitor the liftgate ajar PID while opening and closing the liftgate.
    • Does the liftgate ajar PID agree with the liftgate position? 
    • Yes  : GO to I2.
    • No  : REFER to INTERIOR LIGHTING to diagnose the liftgate ajar circuit.
  2. I2 CHECK LIFTGATE AJAR CIRCUIT 700 (WH/PK) FOR AN OPEN 
    • Key in OFF position.
    • Disconnect: SJB C2280c.
    • Disconnect: Liftgate Ajar Switch C479.
    • Using the following table, measure the resistance between SJB C2280c, rear window wiper motor C476, and liftgate ajar switch C479 harness side:

    • Are the resistances less than 5 ohms? 
    • Yes  : GO to I3.
    • No  : REPAIR the circuit(s) in question. TEST the system for normal operation.
  3. I3 CHECK THE WIPER SWITCH 
    • Disconnect: Wiper Switch C202a.

      Carry out the wiper switch component test. Refer to COMPONENT TESTING .

    • Did the wiper switch pass the component test? 
  4. I4 CHECK WIPER SWITCH CIRCUIT 1205 (BK) FOR OPEN 
    • Measure the resistance between wiper switch C202a-7, circuit 1205 (BK), harness side and ground.

    • Is the resistance less than 5 ohms? 
    • Yes  : GO to I5.
    • No  : REPAIR the circuit. TEST the system for normal operation.
  5. I5 CHECK CIRCUIT 485 (PK/BK) FOR AN OPEN 
    • Measure resistance between wiper switch C202a-10, circuit 485 (PK/BK), harness side and C476-7, circuit 485 (PK/BK), harness side.

    • Is the resistance less than 5 ohms? 
    • Yes  : GO to I6.
    • No  : REPAIR the circuit. TEST the system for normal operation.
  6. I6 CHECK FOR CORRECT REAR WINDOW WIPER MOTOR OPERATION 
    • Disconnect all rear window wiper motor connectors.
    • Check for:
      • corrosion
      • pushed-out pins
    • Connect the rear window wiper motor connectors and make sure they are seated correctly.
    • Operate the system and verify the concern is still present.
    • Is the concern still present? 
    • Yes  : INSTALL a new rear window wiper motor. REFER to WINDSHIELD WIPER MOTOR . TEST the system for normal operation.
    • 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.
