I need help!! On my 1986 442 the left hand brake light works intermittently. The rear wiring harness checks out all the way from the tailights to where it plugs in next to the fusebox. The problem lies somewhere between the brake light switch (which works fine) to where the rear harness plugs into the fuse box. The LH directional works fine as well as the parking lights. The bulbs and sockets check out fine as well. The right hand and third brakelight work fine. Any ideas?
