Does it make any difference where the selector switch is turned? Right off hand, it sounds like the selector switch is malfunctioning. You can try to take it apart to see if they're's anything obviously wrong with it, or you can replace all of the A/C controls (they are all built together).

today, after I "wiggled" a few hoses under the hood, the a/c started to work whenever I let off the gas?? When I accelorated, the air would stop coming out the front vents and shift to coming out the defrost vents??? Could it be a vacuum problem???

I don't think there is any connection between the A/C and vacuum lines. Is your A/C clutch engaging when you are at low throttle and then cutting off at high throttle. Rev your engine to about 2000 RPM and check that out. You might want to pull that A/C cluster to see if there is anything visibly or electrically wrong. As far as I know, the only selector between the different vents is the electrical switch in the cluster.

My air started doing something different today, so I pulled out the controls, and lo and behold...vacuum lines! Guess I was wrong on the last one. Have you figured out the problem?

Did this ever get fixed? If so, how was it fixed I am having the same problem and I have tried in vien to replace vaccum lines, check valves, etc... and nothing seems to fix the problem

I have the same problem in an 2003 Navigator. The A/C works fine when I am idling, but when I step on the gas the cold air stops coming out of the front vents and starts coming out of the defogger vents, when I let go of the gas the cold air comes out of the front vents again. Not the biggest deal but really annoying when it is really hot out. Has anyone found a solution to this? Seems like this problem is affecting a lot of Expeditions and Navigators from a lot of different years out there.
