300 D electrical problems

I have a 300 D and the problem is that all the lights work, but not the turn or emergency signals. Any ideas on what the problem could be?

At the driver's feet there is some oil on the carpet.
Where did that come from?

I sent you a e-mail on your hazard light switch, as far ar your oil problem goes, the only thing I can think of is the oil pressure gauge feed line may be leaking or loose. Be careful in there as you may get a face full of oil. :icon16:
