Need help with Pete turn signal module

2007 Pete, looking for troubleshooting for the turn signal module under the dash. I’ve checked every foot of wire and every connector outside the cab. And all the wire in the cab except 2 feet behind the ducts in the dash.
Randomly blows the right turn fuse, but I don’t have a module to swap out to test it.
Wondering if anyone has diagnostic info for that module.
