If there is bulb not light up, replace the bulb.

3. Cooler switch hole cover

  1. Inspect switch continuity.

    Check the continuity between terminals while switch is pressed, as shown in the chart.

If continuity is not as specified, replace the cooler switch.

If continuity is not as specified, replace the cooler switch.

  1.  inspect illumination operation.

    Connect the positive (+) lead from the battery to terminal 4 and negative () lead to terminal 3 then check that the illuminations light up.

    If operation is not as specified, replace the cooler switch.
