It just happened when the weather got like below 25F here in Michigan, but lately my driver side door won't shut and stay shut. It will shut, but if i push on it from the inside, without touching the handle, it goes open an inch or so. It still is shut, but not all they way...basically i can shove my fingers through the hole and to the outside...and finally, it usually works better when it warms up during the day...is the locking mechanism freezing?...anyone else have this?
