Question about 2005 Jeep Wrangler
My 2005 jeep wrangler, the heat and a/c only blow out of the defrost vents no matter which setting it is set at. (I looked this problem up on-line before and they say that on some models there is a vaccuum hose problem where the cruise and heat vaccuum hoses connect, but I don't have cruise...)
Open your hood and find a "T" connector right near the battery. Follow the line down below the battery (you will have to get under the Jeep). You will see that the line plugs into a 3 to 4 inch section of 3/16" tubing that is plugged onto a black in color, plastic box. Use a razor knife and trim off about 1/2" of this 3/16" tubing as it commonly cracks where it fits on the nipple of the black plastic box. The vacuum cannot build pressure properly with these cracks in this tubing, and therefore cause the selector door to malfunction when operating heat and a/c. It is a quick and easy five minute fix.

The vent selector,(Defrost, Dash,Floor and Dash/floor), works off vacuum. Debri could be keeping from xchanging or vacuum leak.
