Open the hood and detach the negative battery cable remote terminal from the remote battery post before starting work on the headlamp switch. Following this, come off the left end cover, the left instrument panel trim cover and the cluster bezel. After that, remove the three screws keeping the headlamp switch in the cluster bezel and pull the switch out from the bezel. Twist out the sockets now, as long as they are serviceable and fit the switch against the pad so the attachment is tight. Replace the headlamp switch into the light bezel and use three screws to keep it secure during installation. Install the left end cover, left instrument panel trim cover and cluster bezel. Last, fasten the negative battery cable remote terminal to the post on the other battery.
