air ventilation problem

on my 92 pontiac bonneville ssei there is no air coming out of the dashboard or the floor. only to the windshield. does anyone know what can be the problem?

Sounds like a vacuum problem....usually during loss of vacuum, the default position is the defrost......check for vac line disconnected from the vac tank, or a broken line etc.

well I did check n saw that the pink vacuum line from the multi color vacuum hose harness assembly on the ac programmer is disconnected from where ever it goes. where /how do I find the other hose?

You are saying that the pink line is attached to the harness at the programmer, but there is nothing attached to the other end of the pink line?

They sometimes change colors on the supply....usually black....should be under the dash(sometimes attached to a wire harness)......just start car and listen for a hissing vac leak, to find the end.....
