None of my window will go up or down on 2002 Buick Park Avenue

I have a 2002 Park Avenue.

I have replaced the PDA fuse in the fuse panel.
I have checked the 30A fuse in the main fuse box labels door windows

I have replaced the switch assembly (which contains the up/down buttons for the door) with a new assembly from my Buick dealer. The have replaced the Driver Door Module #25721016 with one obtained from a junk yard. No change at all.

The original condition exists.
