Hi All,

I have a '77 911s. The previous owner took the AC system out, but i do not know whether he just disconnected the primary components and just left all the hoses etc...or whether he did the proper job and removed everything properly. I have lost of hoses, components that are connected, patched etc, but i am at loss of functionality.

Can someone educate me or provide a diagram, or video clip or something that explains in laymans terms how 911 air (hot and cold) circulation occurs?? I am looking to understand how the air flows from engine bay to the front of the car, through the air systems etc...

Can anyone also show me what the backdated heat / air circulation looks like in comparison???

Apologies if this is a well answered, documented answer...I appreciate your time.

Thank you!
