1970 dodge dart driver door wont open
Here is another thought as the linkages and latch wear over time (driver's side being used the most, and has the most wear).
Try unbolting the driver's inside chrome latch release handle (7/16" headed bolt..maybe 1/2").
Then grab a vice grip or channel-lock pliers and grab the swing mechanism to get more travel out of the latch release linkages. (hint: you can put a 1" long bolt in it to have something to grab onto)
Good possibility the chrome handle is bottoming on the upholstery/arm rest, and won't push the linkage far enough to release the door latch.
Have someone else lightly push in on the door from the outside as you try to release the latch from the inside.
(As you are lying on your belly on the bench seat, working the linkage).
Could easily unbolt the arm rest at the same time to get it out of the way, with the chrome handle off.
