Will a bad starter cause your car to not start in cold weather?

Yes. I have a difficult time starting my car in cold weather. I took the car to the mechanic and he said that frost can cover the bad spots on the starter and this makes it hard to fire. While you attempt starting the vehicle multiple times a good spot is finally found on the starter and this is why you are finally able to start the car. On really cold days it has taken my car 15 to 20 minutes before I am finally able to start it. I hope this information is helpful.
