Code Salad Deluxe -- MAJOR issues -- HELP!

[soundquest]

 

Our 2007 Acadia had a stroke basically and the car will not move now (although it starts but the idle is erratic with the RPM's fluttering). I can get into reverse and the car will actually move, but in Drive, the throttle does not respond and the car will only move an inch or two at the most. Gauge messages abound -- the usual suspects. Somewhere in the wiring, something has to have gone horribly awry -- either at the BCM (could be right at the harness plug), under the fuse block where all the wires terminate, or a failed ground (or even a bad BCM). In any case, with the number and type of codes I am getting, I am looking for some additional guidance as I know my issue cannot be unique but one of many that has afflicted other Acadias (and similar varieties). Here is the code list (and there are additional codes as well, but these are the big ones):

Those are famous for a water leak right into the right side fuse block and will cause everything you are complaining about. The fuse block is under the right side of the dash and the connectors will be corroded and green if its a water leak.
