    • Is the resistance for all measurements greater than 10,000 ohms? 

    Yes  : GO to  B11.

    No  : REPAIR the circuit. TEST the system for normal operation.

  5. B5 CHECK WIPER OPERATION WITH THE PARK RELAY REMOVED 
    • Disconnect: Wiper PARK Relay.
    • Observe the wiper operation with the PARK relay removed.
    • Are the wipers still operating? 

    Yes  : GO to B6.

    No  : INSTALL a new windshield wiper motor. REFER to WIPER MOTOR .

  6. B6 CHECK WIPER OPERATION WITH THE RUN/PARK RELAY REMOVED 
    • Disconnect: Wiper RUN/PARK Relay.
    • Observe the wiper operation with the RUN/PARK relay removed.
    • Are the wipers still operating? 

    Yes  : GO to  B9.

    No  : GO to B7.

  7. B7 CHECK THE WIPER RUN/PARK RELAY 
    • Carry out the relay component test. Refer to COMPONENT TESTING .
    • Did the RUN/PARK relay pass the component test? 

    Yes  : GO to B8.

    No  : INSTALL a new RUN/PARK relay. TEST the system for normal operation.

  8. B8 CHECK CIRCUIT RRW24 (GN/VT) FOR A SHORT TO GROUND 
    • Key in OFF position.
    • Disconnect: Smart Junction Box (SJB) C2280a.
    • Measure the resistance between windshield wiper RUN/PARK relay pin 1, circuit RRW24 (GN/VT), harness side and ground.

    • Is the resistance greater than 10,000 ohms? 

    Yes  : GO to  B11.

    No  : REPAIR the circuit. TEST the system for normal operation.

  9. B9 CHECK CIRCUIT CRW03 (VT/WH) FOR A SHORT TO VOLTAGE 
    • Key in OFF position.
    • Disconnect: SJB C2280a.
    • Key in ON position.
    • Measure the voltage between wiper RUN/PARK relay pin 3, circuit CRW03 (VT/WH), harness side and ground.
