fog lights

When mine did that it turned out to be a bad switch.

Bad switch, blown fuse, burnt out bulbs. You need to troubleshoot the electrical system. Since you haven't told us the bulbs are known to be good, you will need to pull them to check. I'd check to see if there is electricity to the bulb sockets at the same time. If there is electricity, then the switch, fuses, and all wiring is intact. If there is no electricity, then you have to figure out wherer it is getting lost. If you can check the electricity without physically taking the bulbs out, then that is where you should start.

If there is juice and no light, then you have bad lamps. If there is no juice, you might still have bad lamps, but you'll need to get the juice back first.

no jokes about beemers and their foglights - (European joke)

i found the problem the wires in the fusebox had came off
