I have a 1993 Buick Regal and when I run the aconditioner even on High MAX, I cannot get the air to come out of the vents, it just comes out of the floor vents. Do you suppose it is something in the control on the dash, maybe vacum related?

 

Optional Information:
1993 Buick Regal 3.1 V-6

Look under the hood for a small black plastic hose coming through the firewall. Follow it to it's source looking for any breaks or leaks. Also follow any other lines that branch off because they may go to a vacuum resevoir (storage tank) and a leak there will cause the same problem. Using a vacuum gauge to determine if you have full vacuum at any given point is the best way to find it. You can cut into the line anywhere and splice it back together with a piece of vacuum hose. Find the broken line, you found your problem.

If you don't find any problem in the supply lines, it is possible but rare to have a problem with the vacuum switch itself.
