Got water inside up to my seats while crossing a creek. Got to other side of creek and Hummer was still running fine. Went hunting. Two hours later horn started sounding off. Disconnected battery. Came back later and connected battery, Hummer started up on its own. Cut it off with key. Would not start. Towed to Chevy dealership. They have been letting it "Dry Out" for two weeks. Dash lights all work as well as turn signals ect but it will not start. Any ideas? I

SOUNDS LIKE YOU HAVE IT SOMEWHERE WHERE ALL OF THE DIAGNOSTICS CAN BE DONE.

I HATE TO SAY IT, BUT I'VE SEEN THE NEWER JEEPS IN THE SAME SITUATION, TOO MUCH ELECTRONIC CRAP, MUCH OF IT UNNECESSARY. LOOKS LIKE ALL OF THESE "GO ANYWHERE REPUTATIONS" CAN BE STOPPED WITH JUST ONE DROP OF WATER IN THE WRONG PLACE.

GOOD LUCK!
