Weird things going on with our 2007 ML350 since last rain. First I checked the passenger tail light seals, they seem to be good although water got in the back SAM board area, I checked it and it was ok but cleaned with electrical cleaner anyway. I let everything dry out, obviously the battery was dead.

So, after the dry out period , I was able to jump start the vehicle and all seemed to be fine. Started a test drive, could smell burning, not like engine burning, more electrical I think, could not see any smoke but decided to turn around. Noticed there was no satellite signal although the radio would turn on.
Then the other weird thing is the wipers came on even though they were in the off position and air conditioning was turning on and off. Soon as I pulled into the driveway the fan in front of the engine went full force, then I turned the engine off. What caused this? What should I check? Please provide diagrams to if you can. Thanks alot!

Checked every remaining fuse, they look ok, removed and cleaned front SAM board which looked ok anyway, replaced battery with new battery and started vehicle, no burning smell this time, but again, no satellite or radio signal, wipers come on by themselves, no turn signals, SRS and other warnings come on and off. Is there a specific relay or module that I need to replace? In the meantime, I have disconnected the battery and protected terminals and battery cables so there is no drain.
Please help.
