I have a similar problem to what many refer as the frozen door lock problem. The only thing is I get it randomly and not just in cold weather. I was in outer banks three weeks ago and the door would not open, it was 85 degrees out. From the inside the door does not open, from the outside you have to pull hard to get it to open. The door closes fine every time, I never had a problem with it not closing. Any idea what could be causing this or how to fix this? Thanks
