I wonder what is unique about this particular car's PC board ? A lot of folks had similar issues. The PC circuit design and packaging for all the Christmas Boxcar with exterior LED strings must be similar.
I have the RailKing CP Christmas Boxcar Set with LEDs. The set arrived with one LED String not working at all. Traced the problem to a broken wiring in the LED string as it wraps around the shell and enters the interior at a corner underside. This is a high stress area and obviously damage during assembly. It was a tough spot to repair. It didn't want to accept solder so I used a mechanical fix.
