On my '95 the vents have stopped working. When I turn the switch to various vent positions there is no vacuum sounds, like the doors opening or closing, seems all the air is coming out the defroster duct. I had a little air coming from the dash ducts, then messed with switch, and now have none. Not sure if the dash switch has anything to do with controlling vacuum, or where to check the vacuum on this car. Any ideas of where to start? Or how to check?

Broken vacuum line in the engine bay. Starting at the driver side fender, there's a vacuum tree with 4 vacuum lines coming off it. One is very small, this is the one that controls the opening and closing of those vents. It's probably broken somewhere along where it runs behind the intake.

Same problem with mine. This is the 2nd time it happened. My line in the engine bay is fine. I have been too lazy to try to chase down the leak....

Right on Chris, thanks! It was the little vacuum line behind the intake, right at the connection with the line going into the fire wall. Sure saved me some time, thanks again.

Same here, my engine bay vacuum line is fine, but my vents barely blow out on high. The floor and defroster works fine, its just the vents not blowing as they should.

the line could very well be broken after it goes into the firewall.....if that is the case though, be ready for a royal PITA.
