Default Electrical System Mostly Dead - Steering Lock Stays Locked

I usually keep my Convertible covered, but for the last 2 weeks I have not. I only drive it occasionally and It has rained a lot. Today, when starting, the battery was weak and needed a boost fm my portable booster. Once connected it fired up instantly. When on my short drive I noticed the drivers side floor was really wet. The passenger side was totally dry. Stopped at the business I was visiting, and when I came back out to go home it started immediately. Once home I started a cig outlet powered fan and wet/dry vac'ed the floor the best I could. I also kept it on a battery charger. A few hours later I went out to put the windows up fearing more rain. Turn the key, gauges look normal except it say low on gas - it is not, the HVAC blower does blow, radio doesn't work, windows won't go up, trunk release doesn't work, won't turnover - does even click, the under the hood light is not on (it was on when I first boosted it for my drive). Oh, and the steering does not unlock - I have an uninstalled LMC5 and the LMC5 Unlocker.

I found one of the driver side drain utters was really clogged. It is now cleared

Help

Thanks. I'll keep it on the charger all night. If no relief tomorrow will
replace the battery. Then, I'll come back with codes

Battery loaded tested. It is good. Beyond systems mentioned earlier, I now notice error messages saying "service soon" and "reduced power"

Power seats work, fan blower blows, head lights pop up and on

windows, radio, door locks, don't work, light under the hood doesn't come on

Steering wheel is locked, ignition does not turn engine over

I reinstalled the battery and is like something "reset." The under the hood light is now on, steering wheel is unlocked, and the engine now turns over and fires a about 1 second and then dies. DIC error messages of "reduced power", "check tire pressure", "service soon"

I checked for codes. Each module said "NO COMM." I assume this means no communication.

PS - the passenger side drain hose seems to be clear

Long over due update. I had it towed to the dealer. They found that the water leak had corroded a wiring harness under the drivers seat. They cut the harness connectors out and the hard wired the connections. About 20 dollars in parts but 8 hours of shop labor. All is good now.
