1992 Mercedes Benz S500

Air Conditioning problem
1992 Mercedes Benz S500 V8 Two Wheel Drive Automatic 120000 miles

my 1992 SE500 sollon; AC/ heater will not turn off, and is running down my battery. Even when I pull the fuses under the hood the blower still runs. I have to disconnect the battery every time. I have left it for about a day to reset the computer and connected back up the battery, Still the blower motor is running. I am geting a feed form somewhere else. The rear Window came off its runner. My father disconnected the wire some weeks previous to this. If anyone can help it would be grate. Also if anyone has wireing digrams too it would be grate. Thanks for looking!
