Hey all, does anyone have a HVAC vacuum diagram for a 99 Ram Van? It's the 3.9l V6, without A/C. It currently only blows on defrost, cant switch to any other vents and found multiple broken vacuum lines, but they're all the same color (except for one which I can't find the other half to) so I have no idea what goes to what so looking for a diagram. I even have the service data and it doesn't have one for some reason... or even a picture of what your lines are hooked up to would be helpful. And, if anyone has any experience fixing these lines, what the best method is? Haven't had to fix this style in awhile and can't remember what I did last time lol. Thanks!

 

I thought we had a thread on this a little bit ago

Which vacuum line is this? - DodgeForum.com

 

Match up the colors and use a piece of vacuum line that fits tight to cover the areas that are cut.

 

Ah, I tried finding other posts before I made my own but wasn’t having much luck. I got the black lines figured out, but I can’t find the other half of the white line.. I looked for the valve mentioned in that previous post but can’t seem to find that either
