vacuum line diagrams Help

[lomste]

I have a problem with a vacuum leak on my 1994 c280. I have read all the threads on this and they have been very helpful. I suspect the leak is in one of the actuators behind the dash for the ac system or air diversion flaps. My question is can anybody tell me where I can get a good diagram for all the vacuum lines and colours . I have account with alldata but they dont seem very clear on there. Is the cd out for the w202 yet? If so are the diagrams any good on it and where can I get one?


Thanks for any help.
