air flow question asked another way

The airflow from the AC in my wrangler comes out the bottom vent, the top vent , and the defroster all at the same time no matter how I set the controls. Can someone give me a general idea as to how the airflow is controlled mechanically so I can begin to figure out the problem. I know how to get at the control panel which appears to be vacuum unit I just don't know if its a vacuum problem, control problem or possibly a baffle issue.

When I had an aftermarket system installed on my 99 TJ, I had a similar problem. The shop had to go back in and reconnect some vaccuum tubes that had fallen off at the box end.

I'm not sure of this but I believe the TJs ducts are vacuum controlled. You may want to look around under the hood or under the dash & see if a line's been knocked off.

There is a vacuum actuator on the driver's side of the driveshaft tunnel near where the floor airflow is discharged. Make certain none of the connections have come off and that the actuator is functioning. You should feel a shaft moving in and out of the unit when the airflow selector switch is moved from one position to another.

I would check under the hood at the rear of the intake manifold for a vacuum line off first before going under the dash.
