We get these posts each winter. :? To keep it from happening you need to pull the carpet card off the tailgagte and lube up the actuator rods and latches. Same with our door locks, door latches and handle pulls. If things are already frozen up find an underground parking garage for a day or buy a buddy a 6 pack to use his garage. Scotty's trick worked for me the first time mine froze up, but things weren't nearly as cold as they are right now.
