My PO had the switches re-serviced under warranty just before I picked up my 01 -
I believe we're known to have problems with this....

You have a vacuum leak.

lol mine does this too, a vacuum leak? where and how do you fix it?

Vacuum Leak for sure. I had similar symptoms when I forgot to reconnect my vacuum reservoir after the Highline Fender Installation! Doh!

You'll find that when you engine brake or coast, the AC does what you want, because that's when it creates the vacuum... but when you're at more open throttle, the leak lets the vacuum dissapear and the vents change.

As for how you find the leak... good luck with that one.

I still can't think of the right way to say it... I mean that can't be right how can a Vacuum dissapear? How do you lose nothing???

Redneck it! Buy a can of carb cleaner & start spraying a little on the vac. lines. Start at the intake (be careful, do it with a cold engine, less chance of fire starting)and work ya way down line! You sill get a change in engine RPM when you find it!

Sounds funny, but is actually text book.
The defined loss of vac. is the gain of pressure, or atmosphere.
