Doug, Get a mitivac as others suggested. The chain car parts places have them. Don't pay extra for a fancy metal one. Get some vacuum hose and golf tees for blocking the rubber vacuum lines. I attached the 123 vacuum diagrams, which are in section 80 of the service manual. Start under the hood first to determine which system(s) (e.g. doors, ACC, etc.) are leaking then troubleshoot them one at a time. For the locking system, the main junction under the passenger's floor mat is the place to start and you can check 80% of it from right there. When you find a leaky circuit, disconnect it and stop the line to that circuit with a tee so you can check the rest of the system. Just takes a methodical approach and some patience. After you find the leaks, fixing them is another matter.

Though I have a need to repair the vacuum leaks that are present in the car I know that both the door system and the climate leaks. What do all you do instead of a smoke machine to find these leaks? I find it difficult to just "Try" different spots. Any help on this matter would be nice.:) TIA Douglas _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com -------------- next part -------------- A non-text attachment was scrubbed...
