Had the passenger door lock freeze on it yesterday; it rained most of the day Friday, then the weather turned and dropped down into single-digit temps (F°) last night. It was fine when I backed it out of the garage, but there must've been some moisture inside that froze after we got to the restaurant, and wouldn't shut when my wife got in. We got it to shut by locking the door, but then it wouldn't open from inside or outside. Finally got it thawed out after driving around with the heat on high for ~15 minutes or so, then I turned the heat on in the garage for a while to make sure it dried out too. Worked fine today, which is good because my wife didn't enjoy crawling over seats to get in. Can't say I blame her!
