1999 Ford Expedition V8 Four Wheel Drive Automatic

I've taken my expedition in twice now and still they can't seem to find anything wrong with it. They said it might be my ignition relay so they switched that out and 2 days later it started doing the same thing. Something seems to be draining the battery. Sometimes when I turn it off the blower will stay on and interior lights. Then if its not that, my 4x4 light and my washer fluid light blink on and off (while driving) or sometimes they'll just stay on even though the 4x4 is off. I can turn it off and turn it on and still those two lights remain on. So I'm forced to drive it in either 4x4 low or high till it feels like turning off on its own. You have any suggestions?
