Having problems with your 2001 Hyundai XG300 ?
Headlight come on , replace dimmer bulb but light comes on and goes back out. could it be relay or switch itself. The light and fog light work on driver side but not passenger side. IThis problem occur when I turn on the headlights. I replaced the right dimmer switch. Took out te fuse and relay and replaced them back in. Don't know if you can test relay or not. AS I said the driver side is working.
It sounds as though there is a loose connection on the passenger side. Check socket and switch bulbs from driver and passenger side. hope this helps tim
