Dodge Ram vents only work on floor

[MNmikew]

Just started doing this this spring. No matter where its set, only comes out on floor? Easy fix for a tool challanged person like myself?

What year and what size ram, also engine size?

Many of these are controlled by vacuum. If it is I would bet that there is a broken vacuum supply to the control head. Find the leak and you solved the problem (again if it is controlled by vacuum).

Yep, common problem. On the engine side of the firewall there is the control manifold for the actuator. Usually a hose just pops off.

These guys have you on the right track of checking for vacuum leaks in the hose going to the temp control head. I would check that first, then check for a bad vacuum motor for the mode door, then check to see if you can manually move the door, there maybe an obstruction, like a pen stuck in the door.

Anyone know what this looks like or about where it is?

The vacuum source originates on the passenger side of the intake manifold. You'll see a vacuum line about half way back. Follow that to the fire wall and make sure it is not leaking anywhere. I don't recall specifically where it comes through the fire wall but you'll be able to figure it out when you find it. If everything looks good in the engine compartment then you'll have to find it in the cabin under the dash or pull the controll head to see if there is vacuum at the connector.
