My a/c vents will not blow any air at all out of the vents that blow at your face. The defroster vents work as well as the floor vents. What could be causing this from happening?

I think on the 98 it is controlled by a vacumn switch.
Did you work under the hood and break it or disconnect it.

Possibly so, Do you know around where the switch is located or what it looks like. Thanks so much for the info.

Can anyone tell me where the vacuum hoses for the a/c are at and where the vacuum switch?

Check if there is vacuum to the control head in the dash.
The vacuum hose runs in the main wiring harness.
If there is no vacuum at the control head, check for a broken, or cracked hose in the engine compartment.

Did you have any luck fixing this ? I have exactly the same problem with a 95 i just bought for my son. 95 camaroman
