1998 ram 1500, heater stuck on defrost
 

So i have a 1998 dog ram 1500 that has had an issue where the climate control dial will not bring the dash vents or floor vents in to action. every setting stays on the defroster. i can not really read the diagrams for the vacuum hoses very well, as it appears all the hoses are the same color now. I was told to check the connection on the manifold, but am not sure where to look. Can anyone shoot me a photo of where that may be, please?

Passenger side of the intake, pretty much right in the middle. There are a selection of lines there, one of which will run off to the firewall. If that one is broken/disconnected, you will have only the defrost vents.

jonathon hit my posts on vacuum leaks might help ...almost a must is a hand vacuum pump that has all the little nozzles best way to eliminate areas you dont need to hunt down
