Weird door lock electrical issue!

My door locks, electric mirror, hatch release, horn and interior lights don't work- I keep blowing a 20 amp fuse. My windows work fine. I have a spare harness from another car that has the locks, electric mirror AND ELECTRIC WINDOWS on the same circuit. What am I missing here??

If that fuse blows even without using one of those items connected to it, disconnect one at a time, the wires in that harness until the fuse no longer blows.

Then you will just have to trace the faulty circuit, which probably contains a short to ground.
