Question regarding HVAC/vacuum lines
First of all, I want to thank you all for the kindness and help I have received in the past years. I will leave the C4 community but will stay here on the forum, as I purchased a 2005 C6
. I'm selling my C4, and I want it to be perfect for the new owner. There is only one thing missing: as we installed the new engine we messed up something with vacuum lines/hoses. The HVAC only blows in one direction. I've figured out, that I need a check valve (which I have now), to connect the vaccum to the cruise control and the HVAC, found the cruise control lines, but I'm still unable to locate the vacuum hose going to the HVAC unit. My car is '91 and has manual A/C control. Can someone please help me (maybe with pictures)? Many thanks!

It's PITA to get at usually buried in the main loom that runs back side of motor it's a small hard plastic line and they get brittle and break you might have to unwrap some of the wire harness to find it.
