Air flow switch. Blows all over but where I want it. How to fix?

Hey Guys,
I got a 2003 TJ.
I got the AC working. But I can't get the air to flow through the front vents. It only blows on the floor, or at the windshield. No matter which direction I have the fan direction knob set to.

Anyone have any idea how to fix this issue?

I'm in South Florida, so... it's getting really annoying as the temp rises.

Sounds like a vacuum line disconnected, look under the hood should be a small hard line that goes through the firewall and supply's vacuum to your dash controls. It is usually hooked to a larger rubber line that runs to the intake to supply vacuum.

See Above. No vacumn to the switch puts the valves in the defualt position which is defrost and floor heat.
On a 2003 with a 4.0 the vacumn line you need to look at comes off the side of the intake manifold almost directly below the trottle body it turns into a platic line runs across the firewall to where the AC lines go thru the firewall. There's a few rubber tees and connectors along the way that come loose and sometimes the plastic line itself splits.
