Mine is a 2005 caravan. Same trouble, after the second brake light switch I seen the upper middle brake light was out (the one top of back hatch) Replaced and all was good. This after hours of digging reading schematics checking internet, Also the four way flasher worked but if I shut it off when lights were flashing on they would stay on, shut them off when lights flashed off they would stay off. .when brake lights stayed on after hitting the brakes pulling out the brake light fuse did nothing, but pulling the hazard fuse shut them off. Go figure Hope this helps any one with the same trouble.
