A/C only blows out of defrost and floor vents. No problem with it cooling, just not switching to front vents. I can hear it making noise as though it is trying to switch, but nothing happens. I've been told it is a vacuum leak, but can't locate any lines under the hood or find diagrams showing where these lines might be located. Also might be the blend door actuator has gone bad? Just started this during the past winter. Any suggestions on what to check or replace?

I had to replace the little motor that actuates the door. Mine was stuck on defrost and floor. Took about 10 minutes and $20 bucks from the local salvage yard. It's right under the dash to the right of your gas pedal.
