windows down, but not back up! My first thought is sticky center console windows switches, as in someone spilled soda on them or something like that. So before I take the door panels off to check the windows for mechanical problems, I checked the switches for electrical problems. It struck me as odd that more than one window was misbehaving at the same time for the same reason. Also, when I pushed the window down switch, then went all the way down automatically. That is a function of the convenience module. Then it struck me. The convenience module will open all then windows when you put the key in the driver's door and hold it in the unlocked position for more than a couple of seconds. It is a quick way to cool off the car when it has been parked in the sun on a hot day. The convenience module will also close all the windows if you use the lock the car from the driver's door. I tried it. It worked! The convenience module was badly misbehaving.
Unfortunately it was not to be, or should I say, B2.
