Here's another one...
If the battery has been disconnected both the sunroof and the express-up/down feature of the windows may need to be resynchronized. I copied the following from another post;

"al humphreys
The correct procedure to re-synchronize the windows is as follows. With the key on, raise the window up using only the "first" position of the switch..DO NOT press the switch past the resistance point, into the detent position. When the window is up, hold the switch in that position for 5 sec. Repeat the procedure, putting the window down , again using only the "first" position of the switch, do not press past the resistance point, and then hold it down for 5 sec. This should re-synchronize the window. "
This must be done for each window.
The procedure for the sunroof is similar. Open and hold button for more than 5 seconds then close and hold button again.
