Lights on right side are not working

Question by adam posted 6 months 2 weeks ago in CLK-Class

I have a 2004 CLK 320 and the headlights, turn signal, fog light do not come on at all. This happened once before, went to the Mercedes shop, but then they started working. The manager and I both agreed that we knew the lights were not working when I drove in. Now they are out again, what;s up?
