Occasionally, after driving with AC on at highway speed for at least an hour, the system will start blowing hot air out of the side and back seat vents. This has happened 3 times in the past 3 months. The last incident included blowing hot air out of all of the vents in 100 degree weather. When the car was stopped for about 10 minutes, and then re-started, the system worked properly.

I took it to the dealer last week and they could not find the problem; they expressed surprise that no "codes" were set in the computer. Of course, I was not happy about this, and when I asked what would happen if it continued doing this after my warranty is up (in 4 months), the rep said that I may be asked to "participate" in the cost of the repair.

I am unhappy on 3 accounts:
1- The AC is malfunctioning, causing serious discomfort.
2- The dealer can't find the problem.
3- I may be asked to pay for the fix, even though the problem has occurred under warranty.

Has anybody else experienced this problem ? Any advice ?

If this can't be resolved to my satisfaction, it would offend me sufficiently that I would never consider buying an Audi product again.
