The car runs fantastic but the turn signals, headlights and heating just quit. Mechanics can't find the problem in the wiring but I think it must be a harness or relay.Could it be in the ignition? Several auto electric shops don't want to look at it because of its age. Ford dealers won't touch it. Any suggestions would be great. Different people have been looking at it since January.
