Can anyone help? looking at the front of the car when i turn my lights on the right one works fine, the left one does not. i changed the main bulb and had a look at the sidelight, the sidelight had burned out so i replaced them on both sides i also replaced the main bulb. It looks like the main beem as that dont work either. Anyone help?
Thanks

take the bulbs out the headlights, plug them into the connector for it and turn headlights on see if they come on, if they dont change the bulb with the other side see if that works, if it doesnt then there could be a problem with a fuse/relay or wiring or the headlight switch..
