I *think* my carrier may have broken this morning - rain / snow yesterday and this morning it was 20F. The exterior door handle worked to open the driver door but there was a little more resistance than normal. Had to slam the door hard in order for it to stay latched. While they appear to operate normally, neither the exterior nor interior handles open (unlatch) the door... is this likely the carrier or something else like a frozen latch mechanism.
Update... answered my own question through further searching:
