2003 SL500 Battery Charge has caused weird light warning on dash and accessories to stop working?

I recently had my 2003 SL500 in storage and brought it home, drove fine except the driving lights were flickering trying to come on, so left them off. I got home and put a battery tender on it overnight, green meant charged. When I got in to start it, it 1st said ESP defective, visit shop, so I did the wheel turn back and forth and that warning went away. But now my brake light stays on(Parking Brake warning on dash) Air conditioner won't go to auto or on, stays off, front drivers side HID is out and parking bulb, and driving lights and both side markers up front are out. All it says on dash is bulb in left display and Visit shop on right display? Is the convenience module bad, or battery or what. It had been driving fine, awesome and everything worked before storing it/ What happened? Help.

I would check the bulbs to see if they are really burned out. If they are not you may have a problem with a Front or Rear SAM module. Next it doesn't hurt to disconnect the battery for a few minutes and allow the systems to reset. Lastly do you think the car could have had any water damage? Check trunk and engine bay for water especially near the various modules.
