I've noticed that my commander doors seem to hold water. I've never had another vehicle that's don't that before. After its rained, when I open the door, a lot of water will fall out. Now that the temperature has started to drop, I've noticed the doors are very hard to open. I don't know if it has anything to do with the doors trapping water and freezing or not. Is there a good way to open the doors after they have frozen? Or a better way to prevent them from freezing so hard in the first place?
