Pinpoint Test E: The Rain Sensitive Wipers Are Inoperative

WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Use the correct probe adapter(s) from the Flex Probe Kit when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
  1. E1 CHECK THE INPUT FROM THE MULTIFUNCTION SWITCH 
    • Ignition ON.
    • Cycle the multifunction switch from off through each of the auto/ intermittent settings, waiting 10 seconds between cycling the switch to the next setting.
    • Set the multifunction switch to the wipers off setting.
    • Do the wipers cycle when the switch is changed to each setting? 
  2. E2 CHECK THE RAIN SENSITIVE WIPERS FOR DEFAULT INTERMITTENT MODE 
      NOTE: Make sure the windshield is dry when carrying out this step.
      NOTE: The windshield wipers activate when the multifunction switch is cycled through the auto/intermittent settings. The initial wiper activation after changing the setting should not be considered part of an intermittent wiper operation.
    • Cycle the multifunction switch to auto/intermittent setting 5, the most sensitive to moisture.
    • Do the wipers default to a standard intermittent setting? 
    • Yes  : GO to  E9.
    • No  : GO to E3.
  3. E3 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? 
  4. E4 CHECK THE WINDSHIELD GLASS FOR STREAKING 
    • Ignition ON.
    • Turn the multifunction 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 E5.
    • No  : GO to  E7.
  5. E5 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.
    • Turn the multifunction 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 E6.
    • No  : INSTALL new wiper blades. GO to E6.
  6. E6 RECHECK THE RAIN SENSITIVE WIPERS OPERATION 
    • Turn the multifunction 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 E7.
  7. E7 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 E8.
    • No  : The sensor lens is missing or damaged. INSTALL a new gel-type lens using the rain sensor bracket service kit. TEST the system for normal operation.
  8. E8 INSPECT THE RAIN SENSOR MOUNTING AREA 
    NOTE: The rain sensor gel-type lens can be damaged or contaminated during rain sensor removal, rain sensor bracket separation or incorrect installation.
    • 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  : GO to E9.
    • No  : REMOVE the gel-type lens. INSTALL a new gel-type lens using the rain sensor bracket service kit. TEST the system for normal operation.

      If the concern is still present, GO to E9.

  9. E9 CHECK FOR VOLTAGE TO THE RAIN SENSOR 
    • Ignition OFF.
    • Disconnect: Rain Sensor C914.
    • Ignition ON.
    • Measure the voltage between the rain sensor C914-4, circuit CBP43 (GY), harness side and ground.

    • Is the voltage greater than 10 volts? 
    • Yes  : GO to  E11.
    • No  : VERIFY SJB fuse 43 (10A) is OK. If OK, GO to E10. If not OK, REFER to the SYSTEM WIRING DIAGRAMS article, to identify the possible causes of the circuit short.
  10. E10 CHECK THE RAIN SENSOR VOLTAGE SUPPLY CIRCUIT FOR AN OPEN 
    • Ignition OFF.
    • Disconnect: SJB C2280D.
    • Measure the resistance between the rain sensor C914-4, circuit CBP43 (GY), harness side and the SJB C2280D-22, circuit CBP43 (GY), harness side.
