One problem related to brake light switch has been reported for the 1996 Ford F-150. The most recently reported issues are listed below.
The truck would not shift from park to drive, owner found a blown fuse, #13 on the fuse panel. This fuse has something to do with the brake interlock system. When replacing the fuse it kept blowing. Owner unpligged the switch on the mastercylinder and put new fuse in again. Fuse did not blow and truck would shift. There is a short in the switch or electrical system . This is very much a fire hazzard!!!!!!! still not fixed.
