That wire splits into all four door modules. To isolate the short you will have to access and unplug the door modules one by one to see when the short goes away. Before you do this check the wire loom at the drivers door where it bends going from inside the cabin to the door. Sometimes the wires brake there from all the opening and closing of the door.

This is a severe short to ground. Do you have a routing diagram? Does the orange wire run directly to the door modules? I would think if it were a shorted door module you would smell a burnt odor.

If you still prefer a phone call let me know and I can put that through. It was 5am when you requested it so I didn't see it until now.

Expert:  Ivan Alvarez replied 6 months ago.

Its possible for the module to be shorted without a burn smell. I would recommend to check the wiring first before getting to the door modules. Follow the wiring loom that comes out of the ear fuse box under the rear seat. Look for any places it may have rubbed through.
