Angry 2010 Wrangler unlimited fuse problem

wonder if anyone can help. at wits end! The m38 fuse in the fuse box keeps blowing. I cant even put another 25amp fuse in the slot without it blowing. This fuse is for lock/unlock motors. My auto locks will not work nor will my rear wiper.
I recently had a problem with my driver side door auto window. The blue wire snapper and I had to reconnect with new wiring. I am wonder if the two problems are connected or if someone can add some value as to what the issue may be with this m38 fuse.

Thank You

Disconnect what you did and see if the fuse stays intact.

disconnected

I disconnected what I did and the fuse continues to blow. I unhooked each door from the wiring harness that attaches to the body one at a time to see if fuse will still blow. It still blows with all doors unhooked, back wiper unhooked from electrical circuit.

Somewhere the harness is shorting to ground. It is a tedious process. YOu will need a volt meter to check the leads as well as visually checking for any wire anamolies.

Diagnostic

Does this make sense? This is the write up of the diagnostic. Now the m38 fuse which is power locks only unlocks the doors and does not repeatedly blow while the m24 fuse which operateds rear wiper has no power at all running to it. I checked with a tester.

I have having the exact same problem. Did replacing the fuse box and rear wiper motor solve your problem?

M38 was blowing immediately also but only system not working. Replaced the TIPM today and all is working again.
