I'm almost positive I got the idea of depressing multiple buttons simultaneously from the car's manual.

You may be correct that you should not push two arrow buttons at once, but I'm almost positive the manual says you can push the defrost and the button next to it simultaneously.

The manual is out in the garage, in the cold right now and I just woke up so I'll double check later today.

But regardless, this has nothing to do with my problems since when I push single buttons is when I have the problem. And the problem was present with both push button units.
