The doors to my car stopped opening the drivers door won't open from the outside half the time none of the doors open from the inside the other half of the time only the back door will. Every few days the drivers door will open but that's the one that's normally shut. I thought it was just Frozen and needed to be heated up because one day after I had the car warmed up and was driving for a while the drivers door let me out but other times I'll be in the car for longer with the heat on and it doesn't make a difference. I'm not sure how to fix it and although I'm small enough to I'd rather not have to climb out of the window each time I go out.
