Well, I am happy to say that I solved the blown fuse mystery. I spent much time under the dash inspecting all wires.....found nothing. I then realized that my problems started to develop after I moved my horn from the lower mounting location up to the correct single horn location. The captive washer for the horn bolt pinched the wiring harness to the right front side marker light. Problem solved! I hate electrical Gremlins but it does feel good when you defeat the enemy.
