Need help with A/C Heater control not venting right

I have a 2005 TJ that for some reason it will only blow air out the defrost vent below the windshield. It will not blow out the front, along the doors, or at the floor. I replaced the A/C Heater Control Module. (This is a picture I stole off ebay, but it just shows what I replaced. This isnt my jeep and the control shown is for a jeep w/o Air.)

Swapping the out didnt make the air location work correctly. It still would not switch to blow out the front/face, sides by the door, or at the feet. It would only blow air out the defrost.

I can tell you that when I turn that 3rd mode knob from A/C over to defrost that all the settings work. It will switch from air to outside air to defrost. It just will not change coming out the vents that I want.

Anyone have any idea what could be wrong? or where I can start looking?

I checked the wiring harnesses from the A/C Heater control that lead to the firewall to make sure everything was plugged in and I didnt see any problems. I did have a mouse in the jeep over the winter and I wanted to make sure nothing was chewed.

I'd appreciate the help. Andrea
