I have noticed on my 01 TJ when I am driving with the a/c on sometimes it comes out the wrong vents. The most noticible is when I turn on the a/c and I hit the accelerator. If the a/c is on full blast then I notice it jumping to the vents by the windshield for the defrost. When I hit the brakes then the a/c starts to go through the vents again. At first I thought this might be a vacuum hose issue. however a buddy of mine has a 99 XJ and it does the same thing. My Tj has just under 50K and the XJ has just over 100K. I tried searching the forums and found a lot of vacuum hose issues but nothing exactly like this. It seems wierd to me to be happening on two different but similiar jeeps with a large difference in miles. Thanks for the help, you guys rock!

If all your vacuum lines are ok. There has to be a one way vacuum valve off of the intake and before the actuators to hold the vacuum while under heavy acceleration. Make sure that is not allowing vacuum back through.
