Q: Headlights and taillights don't work

asked by on

My headlights and taillights don't work. The bulbs are OK, so it might be the wires.

Hello. If both of these stopped working at the same time it is usually the switch. This is the most common failure on this car. I would usually check the wiring to the switch for voltage first before replacing the headlight switch, but it is the most common issue.
