If resistance value is not as specified, replace the sensor.

2. Cooler and accessory assy

  1. Inspect blower switch continuity.

If continuity is not as specified, replace the air conditioner control

If continuity is not as specified, replace the air conditioner control assy.

  1.  inspect illumination operation.

    Connect the positive (+) lead from the battery to terminal 2 and negative (–) lead to terminal 3 then check that the illuminations light up.

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.
