I don't why most people calls an open circuit a short circuit. Easy to find out it is an open circuit. Disconnect the battery so voltage is present and do ohms test from the fuse to the switch.
This should be the correct wiring diagram. There are three different versions for different years. Just don't follow the 5 amp fuse circuit it got to be drawn wrong.
