Has had intermittent "window inoperative" issues - that always clear up when I remove the negative battery cable for a couple of minutes - they just start working again

Today, during a misty salty Chicago weather pattern - I had to do that again,

NOW MY WINDSHIELD WIPERS, WINDOWS, SUNROOF AND ELECTRIC PORTION OF THE LOCKING SYSTEM ARE INOPERATIVE

AND WORST OF ALL - THE TRUNK IS STUCK SHUT AS THE LOCK ON THIS MODEL IS 100% REMOTE OPERATED, EVEN THE BLADE KEY ONLY OPERATES A SWITCH


Thus, I'm locked out of the trunk and that is where the bulk of the engine/chassis control fuses and the battery are.

Current status is as follows:

Car runs fine
Car starts fine
Voltage at underhood junction point is 13.2
Heater, AC, defrost OK
Windows inoperative
Door locking system inoperative
Sunroof inoperative
Remote control door locking/trunk inoperative

I need HELP

1. How to access trunk if necessary to effect repairs

2. What the hell just happened? Main control computer? (I'm a parts broker so it won't kill me to replace one......or two "black boxes")

All fuses checked and cleaned

Trunk now is open (used blade key and extra twist of wrist per my service manager and 'voila!)

Master reset now complete (battery ground strap removed

BUT

My ABS and Stability control combination warning light is on, the car is in limp-home mode.

I used the master cylinder as a jump point for my low voltage battery charger last night - could I have fried something when I started the car without removing it this morning?

Best bet is to take it to a workshop that can plug in the analysis computer thingy..  other than that, I got nothing.  Sorry dude.
