basement cold storage winter ventilation problem

We just moved into a new home and we have a large storage room at the back of our finished basement. The storage room is not insulated and the walls exterior walls of the room is the block foundation. When we moved in there was no ventilation in the room and it was very musty and damp. We put in a vent at each side of the room to get air circulating and it seemed to solve the problem in the summer and fall. Now that its winter and below freezing I'm not sure if I should close the vents or leave them open. I was worried about our sump pump freezing (its in the storage room) and cold air escaping into the finished basement because it is in the room so I put some insulation in the vents but I'm now getting condensation on my ceiling in the cold storage area. Should I leave the vents open and allow all the cold air in or is there another solution so I don't get mould building. Any help would be appreciated.
