I have a 2001 Buick LeSabre Limited. All at the same time the power locks, power window and power mirror stopped working on the passenger side door. I am fairly certain that there isn’t a single fuse operating all of these systems on that one door (I looked a the fuse panel and it didn’t appear to be the case). I opened up the door hoping there was a connector that had come loose. All of the systems that have stopped working connect into the “door module”. That is how the part is labeled by GM. I opened up the module and there is a circuit board inside that all the cables connect to. My best guess is that something has gone bad on the the board, but I was wondering if anybody has had any experience with this type of thing? Any help would be appreciated.

Look closely for burned traces, cold solder joints (looks gritty instead of smooth) or corrosion on the board.  
Can you take photos?
