    Do the PIDs correspond correctly with each setting selection? 

    Yes  GO to  G6.
    No  INSTALL a new wiper/washer switch. REFER to Wiper and Washer Switch . If the concern is still present, INSTALL a new SCCM. REFER to STEERING COLUMN CONTROL MODULE (SCCM) .

  6. G6 CHECK THE WINDSHIELD FOR DAMAGE

    • Ignition OFF.
    • Inspect the windshield glass for any cracks, pits or other visible damage around the area of the rain sensor.

    Is any windshield damage present near the area of the rain sensor? 

    Yes  INSTALL a new windshield glass. REFER to REFER to Glass, Frames and Mechanisms .
    No  GO to  G7.

  7. G7 CHECK THE WINDSHIELD GLASS FOR STREAKING

    • Ignition ON.
    • Turn the wiper/washer switch to the low speed wiper setting and while applying water to the windshield surface. Observe the wipe quality, especially around the area or the rain sensor.

    Is any streaking present on the windshield around the area of the rain sensor? 

    Yes  GO to  G8.
    No  GO to  G10.

  8. G8 CHECK THE WINDSHIELD WIPER BLADES FOR STREAKING

    • Ignition OFF.
    • Clean the windshield glass with glass cleaner.
    • Clean the wiper blades with isopropyl alcohol swabs. Wipe the entire length of the wiper blades.
    • Ignition ON.
    • Place the wiper/washer switch to the low speed wiper setting and while applying water to the windshield surface. Observe the wipe quality, especially around the area or the rain sensor.

    Was there noticeable improvement in the wipe quality after cleaning the glass and the wiper blades? 

    Yes  GO to  G9.
    No  INSTALL new wiper blades. GO to  G9.

  9. G9 RECHECK THE RAIN SENSITIVE WIPERS OPERATION

    • Place the wiper/washer switch to the auto/intermittent 5 setting (most sensitive to moisture) while applying water on the windshield above the rain sensor.

    Do the wipers operate when water is applied to the windshield surface? 

    Yes  The system is operating correctly at this time. The concern may have been caused by poor wipe quality on the windshield around the rain sensor.
    No  GO to  G10.

  10. G10 CHECK FOR THE PRESENCE OF THE LENS GEL

    • Ignition OFF.
    • Lightly press the rain sensor against the windshield and release the rain sensor clips.

    Does the rain sensor remain adhered to the windshield? 

    Yes  ATTACH the retaining clips. GO to  G11.
    No  The sensor gel-type lens is missing or damaged. INSTALL a new rain sensor. REFER to Rain Sensor .

  11. G11 INSPECT THE RAIN SENSOR MOUNTING AREA

    • From the outside of the vehicle, inspect the area of the windshield glass where the rain sensor is mounted. The rain sensor contact area should appear black, with no bubbles, air pockets or contaminants between the windshield glass and the rain sensor.

    Does the rain sensor contact area appear black, with no bubbles, air pockets or contaminants between the windshield glass and the rain sensor? 

    Yes  ATTACH the retaining clips. GO to  G12.
    No  REMOVE and INSTALL the rain sensor correctly. REFER to Rain Sensor . TEST the system for normal operation. If the concern is still present, GO to  G15.

  12. G12 CHECK THE RAIN SENSOR VOLTAGE SUPPLY CIRCUIT FOR AN OPEN

    • Ignition OFF.
    • Disconnect: Rain Sensor.
    • Ignition ON.

      • corrosion (replace connector or terminals - clean module pins)
      • damaged or bent pins - replace terminals/pins
      • pushed-out pins - replace pins as necessary
    • Reconnect the rain sensor connector. Make sure it seats and latches correctly.
    • Ignition ON.
    • Turn the wiper/washer switch to the auto/intermittent 5 position (most sensitive to moisture) while applying water to the windshield surface. Observe the wiper operation.

    Do the wipers operate when water is applied to the windshield surface? 

    Yes  The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
