If its locked up, I would pull it out for a rebuild. Most likely the lower bearing on the worm gear is rusted to the housing or to the worm shaft itself, in which case you need to start shopping. With out grease or oil, the lower bearings are the first to go. There is no drain hole for water to get out, and no seal on the input shaft to keep water from getting in. It could be as simple as the upper column bearing is stuck, but to be safe, pull it out for a look.
