No A/C in main vents

[landzero]

Sooo i posted about their being no A/C in the main vents in my 2004 buick rainier i just bought and it only comes out of the defroster and the floor. I Guess this is a very common problem with this model year. I cant find any solid answers though I have since discovered that while i though it was still cycling through the control settings it actually isnt and the only setting that works is the defroster and floor. If you have any info on how to fix this without taking it to the shop that would help.
