car won't lock!

Use either a circuit light, or a DVOM, and test each wire's continuity to ground to see if its one wire in particular that is having the issue, then back track it through to the car body, and see if the harness was pinched somewhere between.

If it's just one wire, you can easily splice in a new wire to fix it.
Enough testing, and you might even be able to find the break point, and fix it there.

BC.

I was thinking if the harness was a little more snug at the connection that this would solve it. Any ideas??

if wiggling or applying pressure at the connector has influence on the behavior/fault of the problem, then the root cause should be there and not some distance down the harness.
the electrical connection within the connector is with a pin and a socket. it is possible that one socket have become "larger" so that the pin/socket is not making good contact. I think this is not likely. connectors for use in harsh environment is designed to have the body of the connector take the load so that the pin/socket do not. by the time the connector body is locked in place, pin/socket should be making per-design contact with no mechanical stress.
it is possible that moisture has gotten into the connection and making one or multiple contacts dirty. but since you have mated/demated this connector many times, it should have rubbed the rust off.
it maybe that one socket at the harness end is not fully seated in the connector. Take a look at the harness connector and see that all electrical connections (sockets) are at the same level.
I still think the problem is with the connector pins/DLM PWB solder joints. These pins at the PWB also functions as a mechanical anchor for the DLM side connector; so wiggling the harness will wiggle these pins.
any chance you can take apart the DLM and post close up photo of the solder joint?
