Thank You, But my car has not been washed for a long time. it happened a couple nights ago when the temp went to 0 (zero) The next morning i went to start the car an the handle button was really stiff, hard to push in, when unlocking with key it very slow an stiff like. Car started But could not shut the door, would not latch, even slamming a few times. Had to wait close to an hour with heater running, then it closed. I want to avoid this happening again in the future. An my heater blows only warm air, Not hot
