Unfortunately, I don't have all the diagrams any more. But maybe MB Doc does (By the way, Thanks MB DOC for whatever you sent, I don't remember specifically what it was, but everything helped). Also unfortunately, removing the dash was the ONLY way to reach most of the vacuum actuators. Once removed, it is relatively easy to replace them. I replaced all of them (around $200) because I didn't want to go back and do this job again. If you have the diagrams, it is a long but relatively straightforward job. It took me most of the afternoon. Just do it step by step. I took pictures with my digital camera along the way. Didn't really need them in putting it back together, though. It's pretty intuitive. Removing the steering wheel and air bag was one of the scarier things to do, but do searches on this site and you'll understand what you need to do. Don't turn the ignition switch while the airbag is disconnected!!! You will get an SRS light. On the positive note, you don't have to be a MB trained assemblyworker to get a squeek free dash. My dash is as tight as ever. By the way, I'm not necessarily recomending anyone do this. This is definitely a do at your own risk. It's a sense of accomplishment, obviously, IF you get the results you want. Best of luck.
