Solved.
The moron that installed the aftermarket speakers used screws that were too long, and twisted one into the wire bundle that runs in/out of the front passenger side door.
Thanks for the rapid response, Kevin.
I guess I know what I'm doing this weekend.
As an afterthought, I *should* be able to do it with one fuse. Pull all the actuators and reconnect them one at a time until the fuse blows. Yes?
I'll bet good money now it'll the last one.
This is the fuse under the dash labeled "DOOR". If I replace the fuse everything works as it should for one or two cycles of the locks. Then the fuse blows again.
Ideas, comments, suggestions please?
