My battery went dead and when it was charged none of the door locks would work in the H3 or even the remote. Also every window would roll down except for the drivers side. I read that when the battery gets weak then the computer shuts down nonessential electronics based on importance. Simple fix is to take the positive lead off your batter for about 30 mins or so and reconnect...get in and fire it up and it all worked back to 100% Set your clock and back to factory setting. Taking the battery lead off resets everything! I did this today and all is well!! good luck!
