Fuse blows

Are you referring to the tail light fuse? That is the only one shown in the fan circuit, but there is a lot of stuff on it for a ten-amp fuse. Here is the wiring diagram I found. If you find it too hard to read, I will blow it up so I can read it better, then I will write the circuits in a list.

A simple trick to finding a short is to replace the blown fuse with a pair of spade terminals, then use small jumper wires to connect them to a twelve volt light bulb. A brake light bulb works well. When the circuit is live and the short is present, the bulb will be full brightness and hot so be sure it is not laying on the carpet or against a plastic door panel. Now you can unplug electrical connectors and move things around to see what makes the short go away. When it does, the bulb will get dim or go out.

I will try this, then return with the results. Thank you.
