Check to see that there aren't any crimp pins that have backed themselves out of the connector. If everything doesn't line up when a connector is plugged back in, sometimes it will shove a crimp pin out the back of the connector shell. Not likely, but I've seen it happen before and it's always good to look for the easy to spot stuff whenever I hear "I unplugged something and it doesn't work after I plugged it back in".

Whatever it is, it's probably something simple. It may not be simple to spot, but it should be simple to fix.
