Here is a write up on how to fix them

Do-It-Yourself Door Lock Actuator Repair - Ford Powerstroke Diesel Forum

A lot of people use zip ties or something like that to out he cases back together we drilled out the holes and put in small stainless nuts and bolts and like I said it works great no sense in spending a ton on OEM actuators or buying the cheap ones that will wear out quickly

Thanks lowdown...gotta print that off. Id get a headache trying to read all that on my phone.

Could a thermal resistor be put in place where you put tge copper wire?

I'm honestly not sure, we just happened to have a piece of copper sheeting laying around in the shop that was the same thickness as the old pieces so we cut em out with a band saw and filed them down to the exact size. I don't know enough about electrical stuff to have any clue about thermal resistors lol
