I found an 04 MM but the panel that has the controls for the windows, side mirrors, and lock/unlock is coming undone. I am trying to figure out what it would cost to replace it and can someone who is rather handy do this. I assume there are some tabs on the inside and one of them broke. I also assume the most difficult task would be to make sure the wires go back to the right switch.

Some other questions:
#1 What is this part called?
#2 Is the availability of one easily found? Maybe I can figure this out after knowing what it is called.
