Question
The air blows out of the panel[beneath the windshield]but not the vents.Also how would I go about checking to see if a hose is disconnected.

Answer
Hello,

I can tell you that you have a vacuum leak, but without being at the car and listening for it or having a vacuum routing diagram for that specific car, I really have no way of helping you.

Could possibly be a computer issue for the heating and A/C.

Did this just happen or were you doing something to the car and then noticed the problem?
