1987 560sl vacuum question
Hi!, on my 1987 560sl, I've been doing some climate control repairs, and noticed that the fresh air vents don't work. I found a red/blue vacuum line going from the passenger side vacuum pots that is not connected to anything. Also, on the back of the fresh air/recirc. switch, there is a vacuum line going to the back side of it, into a rubber connecter that has 3 holes, and only a solid red vavuum line going to it. Are there any other vacuum lines that are supposed to go there as well? One thing I can't seem to find is a good picture/diagram of the vacuum system. If I had a diagram/picture, I'm pretty sure I could figure it out!
I'm sure someone has dealt with this in some form or another, and any help would be appreciated!
Thanks,
