I have a 2001 jeep cherokee sport. Have had a lot of rain lately with water coming in around windshield and going to floorboards, so I do not know if this is related, but last night my headlights would not turn off although all parking lights did. Had to disconnect the battery. This morning the headlights went off while engine was running but when I turned the engine off the headlights came back on. Anyone have an idea?
