Q: Door locks, dome light, and headlights not working.

asked by on

Headlights do not work and changing the switch had no effect. Door locks and inside dome lights are also not functioning.

Hi there. Electrical issues are fairly common on your vehicle. If all of these circuits quit working at the same time most of the time it is due to a failure in the fuse box. The only way to diagnose this is with a digital multimeter and running some electrical tests. You should enlist the help of a certified mechanic to do this, like one from YourMechanic.com.
