I got your message the first time you sent it. It should be obvious you are loosing vacuum to the HVAC controller. As you loose vacuum the system goes into default and stitches back to your setting when vacuum returns. I think you're going to find a bad check valve and/or vacuum leaks of some sort in the HVAC system. Hope this helps, Rex

Central America Standard T Subj: a/c controls goes from panel to floor Hi All When running the A/C on my 1987 Shelby Lancer the duct work flap goes from panel blowing, to blowing air to the floor when I go from vacuum to boost, if let off the gas and start pulling vacuum again it goes back to blowing out of the panel, back and force, back and force its getting annoying, there's gota be something wrong.
