123.130 ac/heat vaccum diagram?

[mark300d]

Hello,
can anyone help me in obtaining the vaccum diagram for the air conditioning and heating system on a 78 300D non-turbo? The car has the climate controller with the vertical push buttons. I have the MBZ chassis books Volume 1 and Volume 2 but they do not cover the system. I need to find where my system is leaking air and what all the tubes do.
Thanks.
Mark.

Please e-mail me with your specifics. I have the separate heating and AC manual for my 1977 240D which should cover yours also.
