1994 Other Mercedes Benz Models TURN SIGNAL

You may want to check the turn signal relay first. After locating the relay in the fuse box pull it out and replace it with another relay from another slot that is the same part number. It may be your horn relay for example. After switching the two, turn the vehicle on (2nd accesory position) but don't start it, then check your turn signals. If they work then you need to replace the relay. If they don't you may have a failed combination switch (the turn signal lever assembly) that will need to be replaced.
