ac stop blowing

[tinodtank]

so maybe someone can help, driving down the road and heard a noise like something fell inside the dash then ac stopped blowing on the face blowers. Air only comes out top vents like it on defrost, its cool air, just won't blow on face. Ac in the back still bows and cools. I checked all fuses and under dash can't see anything out of place. What do y'all think? never mind read the guys post under me sorry
