I was having the same problem on my 1994 Jeep Cherokee Sport. Searched fuse panels and switches, finally got fed up and took it to a mechanic. After hours of inspection they found that a quick connect (wiring harness) for the wiring from the switch to the headlights had a dead short and melted together. It was located in dash behind the switch. They had to cut half of the connect off and directly wire some of the wires together. Problem sloved after about $250 in labour.
