Wiper Switch: Inspection

WARNING: This page is about a different car, the 2008 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
  1. INSPECT WINDSHIELD WIPER SWITCH ASSEMBLY 
    1. Check the front wiper switch.
      1. Measure the resistance of the switch.

        Standard resistance 

        FRONT WIPER SWITCH ASSEMBLY

        Tester Connection Switch Condition Specified Condition
        E10-1 (+S) - E10-3 (+1) INT Below 1 Ω
        OFF
        E10-2 (B) - E10-3 (+1) MIST
        LO
        E10-2 (B) - E10-4 (+2) HI

        If the result is not as specified, replace the switch assembly.

    2. Check the front washer switch assembly.
      1. Measure the resistance of the switch.

        Standard resistance 

        FRONT WASHER SWITCH ASSEMBLY

        Tester Connection Switch Condition Specified Condition
        E9-2 (EW) - E9-3 (WF) ON Below 1 Ω
        OFF 10 kΩ or higher

        If the result is not specified, replace the switch assembly.

    3. Check the intermittent operation.
      1. Connect the voltmeter's positive (+) lead to terminal E10-3 (+1) and the negative (-) lead to terminal E9-2 (EW).
      2. Connect the battery's positive (+) lead to terminal E10-2 (+B) and the negative (-) lead to terminal E9-2 (EW) and E10-1 (+S).
      3. Turn the wiper switch to the INT position.
      4. Connect the battery's positive (+) lead to terminal E10-1 (+S) for 5 seconds.
      5. Connect the battery's negative (-) lead to terminal E10-1 (+S). Operate the intermittent wiper relay and check the voltage between terminals E10-3 (+1) and E9-2 (EW).

        Standard voltage: Refer to  Fig 2 .

        If the result is not as specified, replace the switch assembly.

    4. Check the front washer operation.
      1. Turn the wiper switch OFF.
      2. Connect the battery's positive (+) lead to terminal E10-2 (+B) and the negative (-) lead to terminals E10-4 (+S) and E9-2 (EW).
      3. Connect the voltmeter's positive (+) lead to E10-3 (+1) and the negative (-) lead to terminal E9-2 (EW).
      4. Turn the washer switch ON and OFF, and check the voltage between terminals E10-3 (+1) and E9-2 (EW).

        OK: Refer to  Fig 3 .

        If the result is not as specified, replace the switch assembly.

    5. Check the rear wiper switch.
      1. Measure the resistance of the switch.

        Standard resistance 

        REAR WIPER SWITCH

        Tester Connection Switch Condition Specified Condition
        E9-2 (EW) - E9-6 (CIR) INT Below 1 Ω
        E9-2 (EW) - E9-7 (+1R) ON
        E9-2 (EW) - E9-6 (CIR) OFF 10 kΩ or higher
        E9-2 (EW) - E9-7 (+1R)

        If the result is not as specified, replace the switch assembly.

    6. Check the rear washer switch.
      1. Measure the resistance of the switch.

        Standard resistance 

        REAR WASHER SWITCH

        Tester Connection Switch Condition Specified Condition
        E9-2 (EW) - E9-7 (+1R)
        E9-2 (EW) - E10-5 (WR)        		 ON Below 1 Ω
        OFF 10 kΩ or higher
