A buddy of mine has a 70 Trans Am where the driver's door will not open now from the inside or outside, The door handles seem to feel ok and the door lock seems to be working ok, but we are unable to open the door. The door hardware appears to be the same as my 85 El Camino. I'm not sure we can even get the door panel off with the door shut. Has this happened to anybody on their El Camino? Any suggestions for getting the door open so we can pull the door panel to see what needs repaired?
