Being new to the benz world, I decided to open up the leakign servo box. I figued if its already broke, then what harm is there?

I found that the gasket material had warped a bit. I used form-a-gasket on both sides of the gasket and bolted it all up. No leak so far, but then again no idea if the servo functions (yet).

If you decide to take this on, I would suggest that you have a digital camera nearby and take lots of pictures for reference. It took me a couple of hours to make logic out of the parts.

The reason I don't know if it works or not is that the air on the car doesn't work and when I pushed the defrost button in, it sent a loose part into the blower. That by itself tells me something must be working. So Sunday is now dedicated to finding what fell into the blower.
