A cold-soldered connection doesn't have anything to do with the outside temperature. It simply means that the solder joint was not completely flowed to the degree it needed to be to make a good solder joint. It usually leads to the joint breaking apart or partially breaking apart down the road.
I'm not saying that you don't still have a wiring problem. I'm just saying that your definition of a cold-solder connection isn't quite right.
