Have a problem with my a/c...when activated, air comes out of everywhere it is supposed to except the front dash. It comes cold out of the defrost vents, and the rear a/c???/ What is the problem and fix?????? I live in Phx, AZ(HOT!!!)
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.
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.
