My Girlfriend just bought an 87 190E 2.0. She's had it for a couple of weeks so far with no problems.
Yesterday her turn signals stopped working. I wont be seeing her until the weekend, so I had her check the fuse because I know how funny these can be. It looked good and her horn still works (share the same fuse).
Her hazards still work, so the flasher relay is good.

I've been looking at my w126 electrical manual, and the only thing I can think of, assuming both the w201 and 126 are similar, is that the combination stalk itself is faulty, or the wiring to it has broken/become disconnected.

Any other helpful suggestions?
