Pinpoint Test A: The Wipers Are Inoperative - Windshield

WARNING: This page is about a different car, the 2007 Lincoln MKX and 2007 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
  1. A1 CHECK CIRCUITS SBB58 (YE/RD) AND CBP45 (YE) FOR VOLTAGE 
    • Key in OFF position.
    • Disconnect: Windshield Wiper Motor C1552
    • Key in ON position.
      • Fig 1: Measuring Voltage Between Windshield Wiper Motor C1552-5 & C1552-8, SBB58 (YE/RD) & CBP45 (YE)

    • Measure the voltage between windshield wiper motor C1552-5, circuit SBB58 (YE/RD), harness side and ground; and between windshield wiper motor C1552-8, circuit CBP45 (YE), harness side and ground.
    • Are the voltages greater than 10 volts? 
    1. YES  : Go to  A2.
    2. NO  : VERIFY that BJB fuse 58 (30A) and SJB fuse 45 (5A) are OK. If OK, REPAIR the circuit(s) in question. TEST the system for normal operation.
  2. A2 CHECK CIRCUIT GD120 (BK/GN) FOR AN OPEN 
    • Key in OFF position.
      • Fig 2: Measuring Resistance Between Windshield Wiper Motor C1552-6 & C1552-3, Circuit GD120 (BK/GN)

    • Measure the resistance between windshield wiper motor C1552-6, circuit GD120 (BK/GN), harness side and ground; and between windshield wiper motor C1552-3, circuit GD120 (BK/GN), harness side and ground.
    • Are the resistances less than 5 ohms? 
    1. YES  : Go to  A3.
    2. NO  : REPAIR the circuit(s) in question. TEST the system for normal operation.
  3. A3 CHECK THE MULTI-FUNCTION SWITCH 
    • Disconnect: Multi-function Switch C202
    • Carry out the multi-function switch component test.
    • Did the multi-function switch pass the component test? 
    1. YES  : Go to  A4.
    2. NO  : INSTALL a new multi-function switch. REFER to STEERING COLUMN SWITCHES .
  4. A4 CHECK CIRCUIT GD116 (BK/VT) FOR AN OPEN 
      Fig 3: Measuring Resistance Between Multi-Function Switch C202-15, Circuit GD116 (BK/VT) & Ground
      GF0026528Courtesy of FORD MOTOR CO.
    • Measure the resistance between multi-function switch C202-15, circuit GD116 (BK/VT), harness side and ground.
    • Is the resistance less than 5 ohms? 
    1. YES  : Go to  A5.
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
  5. A5 CHECK FOR CORRECT WINDSHIELD WIPER MOTOR OPERATION 
    • Disconnect all windshield wiper motor connectors.
    • Check for:
      • corrosion.
      • pushed-out pins.
    • Connect all the windshield 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  A6.
    2. 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.
  6. A6 CHECK THE WINDSHIELD WIPER MOTOR 
    • Key in OFF position.
    • Disconnect: Windshield Wiper Motor C1552
    • Carry out the Wiper Motor - Windshield  component test as outlined.
    • Did the windshield wiper motor pass the component test? 
    1. YES  : The system is operating correctly at this time. Concern may have been caused by binding or incorrect pivot arm adjustment. TEST the system for normal operation.
    2. NO  : INSTALL a new windshield wiper motor. REFER to Wiper Motor - Windshield .
