I am just about to go out and see how hard it is to get to my turn signal/wiper lever on the left side of the 1995 e320 to see if I can see why it is acting up. Sometimes the turn signals will work and sometimes they will not. If I beep the horn it will make the turn signals work, sometimes. Same deal with the wipers. First thing I thought of was the fuse but it appears that they are on seperate fuses. I don't know what else it could be but a flaky connection in the switch somewhere.

Any advice on going in there to clean it or replace it?

Thanks very much,
Jim Lee

Most likely its the combination relay, located just behind the fuse panel in the engine compartment (driver's side). It's called a combo relay because it servers as a relay for a number of functions, including turn signals, hazard flashers, and intermittent wiper operation.

I replaced mine about 4 years ago for around $100.

Wow, that's cheap. The W140 version of that relay is $430.
