I have a 1989 Chevy Corsica--4door with about 140,000 miles on it. IT DOES NOT HAVE ELECTRIC LOCKS. My problem happened due to a series of ice storms that made two of my doors so they would not open from the outside. My driver's door will not open from the out or inside! I have to open the driver's front door by using the rear door to open the passenger front door and then crossing over to the driver's seat so I can drive my car. It is a terrible pain in the rear and I can't figure out how to open the driver's door so I can try and fix it since I cannot open the door at all.
