97 jeep cherokee doesn't blow any air from dash vents only from floor and top of dashboard any solutions?

It could be your controls if when u switch from feet to face to defrost, just thinking outloud but you can try and take it out and mess around in there see if anything is unplugged or don't look right. Good luck!

There is a vacuum line going to a flapper inside your dash, it determines where the air goes i.e. the floor and dash or the vents. You can see if you have a vacuum leak when your ride is running or when you shut it off you will here a sucking whistling sound, that's a vacuum leak.. the tubing is like .50 a foot, replace it and clean the control flapper and I bet it will work..
