My Climate Control Only Blows Defrost

I have a 2000 Chevy Astro Van with 115,000 miles. The front climate control system recently became stuck in the defrost setting only. I can't get this to switch to other vents in the front. The back climate control works fine. It's just the one in the front. Could this be a problem with the switch, or maybe a stuck valve inside the dash? I don't know where to look to solve this problem. Thanks.

Look under the hood for a broken vacuum line.
