2004 Jeep Wrangler Unlimited Defrost Problem

On my '04 Jeep Wrangler Unlimited my AC/Heat only works on Defrost now no matter what selection I change it too. The fan speed is still varible though so I don't think its the blower. From what I gather on the forums this is most likely an issue that the default setting being Defrost and there is probably a vacumm leak somewhere. Since I have very little mechanical experience I just can't visualize what I am supposed to be looking for under the hood by the text I have read. I was hoping someone could post a picture of their jeep under the hood and point out the cables/tubes I should be inspecting.

My defrost is working well though so good that it caused a stress crack in my windshield over the weekend from the extreme external cold to the heat of the defrost.

Thanks in advance.
