Why Does Ac Blow Air Through Defrost Vents And Will Not Blow Air Into Cabin?

Hey,

I've a 1992 Camaro RS. The a/c had been working very well till today. My a/c that had worked fine in the morning on my way to work suddenly doesen't blow air through the regular vents.
I found a vacuum leak and fixed that but the a/c still comes out everywhere BUT the regular vents. Even when the selector is set to "Vent" i don't have anything through the vents.

Any suggestions?

Thank you in advance for any help.

Kenny

Thank you John. It was the A/C selector mode switch. Thank God that JaysZ28 had one in a coffee can somewhere. It worked. The one in the car just crumbled in Jay's hand.
