Pinpoint Test Q: The Wipers Are Inoperative

WARNING: This page is about a different car, the 2004 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
  1. Q1 CHECK CIRCUITS 75-KA8 (YE/RD) AND 30-KA8 (RD/BU) FOR VOLTAGE 
    • Key in OFF position.
    • Disconnect: Windshield Wiper Motor C125.
    • Key in ON position.
    • Measure the voltage between windshield wiper C125-5, circuit 30-KA8 (RD/BU), harness side and ground; and between windshield wiper motor C125-8, circuit 75-KA8 (YE/RD), harness side and ground.

    • Are the voltages greater than 10 volts? 
    1. Yes  : GO to Q2.
    2. No  : REPAIR the circuit(s) in question. TEST the system for normal operation.
  2. Q2 CHECK CIRCUITS 31-KA8 (BK/BU) AND 91-KA8 (BN/RD) FOR OPENS 
    • Key in OFF position.
    • Measure the resistance between windshield wiper C125-6, circuit 31-KA8 (BK/BU), harness side and ground; and between windshield wiper motor C125-3, circuit 91-KA8 (BK/BU), harness side and ground.

    • Are the resistances less than 5 ohms? 
    1. Yes  : GO to Q3.
    2. No  : REPAIR the circuit(s) in question. TEST the system for normal operation.
  3. Q3 CHECK THE MULTIFUNCTION SWITCH 
    • Disconnect: Multifunction Switch C202.
    • Carry out the multifunction switch component test.

      Refer to COMPONENT TESTING .

    • Did the multifunction switch pass the component test? 
    1. Yes  : GO to Q4.
    2. No  : INSTALL a new multifunction switch. REFER to STEERING SYSTEM for the removal and installation procedure.
  4. Q4 CHECK CIRCUIT 31-KA19 (BK/RD) FOR AN OPEN 
    • Measure the resistance between the multifunction switch C202-2, circuit 31-KA19 (BK/RD), harness side and ground.

    • Is the resistance less than 5 ohms? 
    1. Yes  : GO to Q5.
    2. No  : REPAIR the circuit. TEST the system for normal operation.
  5. Q5 CHECK CIRCUITS 8-KA8 (WH/RD), 10-KA8 (GY/RD), 8-KA11 (WH/BK) AND 8-KA10 (WH/GN) FOR OPENS 
    • Using the following table, measure the resistance between the multifunction switch C202, harness side and the windshield wiper motor C125, harness side:
      CONNECTOR PINS DESCRIPTION

      Multifunction Switch C202 Windshield Wiper Motor C125
      pin 1, circuit 8-KA8 (WH/RD) pin 10, circuit 8-KA8 (WH/RD)
      pin 3, circuit 8-KA10 (WH/GN) pin 9, circuit 8-KA10 (WH/GN)
      pin 4, circuit 10-KA8 (GY/RD) pin 11, circuit 10-KA8 (GY/RD)
      pin 6, circuit 8-KA11 (WH/BK) pin 1, circuit 8-KA11 (WH/BK)

    • Are the resistances less than 5 ohms? 
    1. Yes  : GO to Q6.
    2. No  : REPAIR the circuit(s) in question. TEST the system for normal operation.
  6. Q6 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? 
    1. Yes  : GO to Q7.
    2. No  : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. TEST the system for normal operation.
  7. Q7 CHECK THE WINDSHIELD WIPER MOTOR 
    • Key in OFF position.
    • Disconnect: Windshield Wiper Motor C125.
    • Carry out the windshield wiper motor component test as described.
    • Did the windshield wiper motor pass the component test? 
    1. Yes  : The system is operating correctly at this time. The concern may have been caused by binding or incorrect pivot arm adjustment. REFER to WINDSHIELD WIPER . TEST the system for normal operation.
    2. No  : INSTALL a new windshield wiper motor REFER to WINDSHIELD WIPER .
