This evening I left work and found my 2-door car covered with a little ice and a lot of snow. I was able to unlock the driver side door, but the door was frozen stuck. I pulled on the handle and the door wouldn't budge. I tried pounding along the edges of the door frame with my hand to see if that would help loosen it, but that didn't help as I pulled on the handle again. The car is fairly old and the door handle seems a little weak, so I didn't want to pull too hard for fear of breaking off the handle.
The passenger side door was frozen stuck too, although the handle isn't as weak as the driver side handle, so eventually I was able to pull the door open. Then I was able to open the driver side door from the inside.
In case this happens again in the future and I am unable to open either door, what should I do?
