You Chevy Lumina utilizes a multifunction switch which controls a variety of car elements, including headlights, turn signals and emergency flashers. If you notice any or all of these functions operating erratically, or not working at all, it is possible your multifunction switch has gone bad. The multifunction switch is located inside your steering wheel column and is fairly easy to access. Replacement will take you approximately 30 minutes.
Open the hood of your Chevy Lumina and use your socket set to remove the negative battery cable.
Insert the trim tool between your steering wheel column and the trim and begin to pry the trim up. Work your way along the column until all the trim is pried up and way.
Squeeze the two tabs in on the back of the multifunction switch's wiring harness and unplug it from the back of the switch.
Insert your screwdriver into the switch retaining screw and twist it to the left to remove it. Take out the old switch and set the new one in place. Return the switch's retaining screw and then plug the wiring harness back into the rear of your Lumina's new multifunction switch.
Use the trim tool to replace the trim along your steering wheel column. Replace your Lumina's negative battery cable.
