For your safety, first remove the negative battery cable and give the ceramic dimmer resistor time to cool if it has been used. First, lift out the cluster bezel and afterward, remove the three screws that hold the headlamp switch bezel in place. Pull the headlamp switch and bezel out until you can see the two connectors. Then unplug these connectors. Pull the knob on the switch out to turn it ON, then squish the button on top of the switch body. Whilst still securing the release button, pull the entire unit out by turning the control knob. After that, take out the nut under the spanner, disconnect the bracket and bezel from the switch and remove both pieces. For installation, put the switch bezel and mounting bracket onto the headlamp switch, then install and tighten the spanner nut. Pierce the bezel with the shaft of the control knob and shaft unit and then place everything in the headlamp switch, making sure it is pushed all the way. Mount the headlamp switch to the instrument panel and link up the wire harness connectors. Place the headlamp switch bezel on the panel and use the three screws to connect and tighten it to 2.2 Nm (20 in. lbs.). After that, place the cluster bezel back in its place and attach the negative battery cable again.
