The vaccum line going to the heat/ac control switch is broken. does anyone have a picture or can tell me where the line enters through the wall into the cab under the dash? My contoller is stuck in the defrost mode.

 

Take out the control **** section and you will see all the vac lines. You can perhaps trace it from there. It is an easy removal.

On the drivers side directly left of the master cylinder is a vacuum port with a green cap. Now the line directly behind it also reduces to a very small kind of hard black plastic line and goes into the cab using the same heater core port through the fire wall. Here is a picture of the line under that "T" and the little line reduction.

 

Thanks for the response, the smaller hard plastic line is what remains with about 8" dangling from where it broke off anyway you can show a photo of the area it enters the firewall where the heater core port is located.

 

I don't have a Durango anymore so I can't just go take a picture but if you follow the red water line off the water pump that you see on the right of this picture (yours will be black), where it enters the cab (the one on the right) is where that line runs into the cab then up to the switch.
