Phaeton :: AC Stays On Continuously, At About 68 Degrees

During my first year as a Phaeton owner, I had AC problems and tried to have it fixed. As usual, when you have the problem, it just seems to go away when you take your car into the dealer. It happens when I go on any extended trips, and have the AC on continuously, at about 68 degrees. There were four of us traveling yesterday and returning home today. The outside temp was 87 degrees, After driving for two hours, the cool air stopped coming out the vents. It was working real hard to provide a strong air sound that was harnessed only in the dash, and even when I lowered the temp it would not come out the vents.

I remember several years ago in an American Lincoln town car when we traveled from Florida to Georgia to avoid a hurricane, and it turned out we had no air when we got to GA. It was something called a blendor and I don't know if my Phaeton has any such monster.

I had the same problem in 2006 when I had to drive to NJ to bury a relative, and all through the funeral (in July when it was hot) I could not get any cool air to come out. The noise in the dash again seemed to tell me the air was blowing somewhere else, but I have no clue. Again took it to VW service, but could not recreate the problem. I also tried all the other positions as to where the air should come out (i.e., straight at your upper torso, down at your feet, etc.) but nothing worked.
