Locked Door Won't Unlock Or Open
So, I have a 1969 GTO and was having no issues operating the doors until I accidentally depressed the lock button on the driver's side door with my elbow while sitting in the car. While this should have not been a big deal, I am now unable to unlock the door, neither from the inside nor the outside, which also means that I can no longer open the driver's side door.
I've tried to pull up on the lock button pretty hard but it won't unlock. I'm afraid of pulling any harder for fear of breaking something. Using the key has also not worked. And with the door closed, I can't get the inside door panel off to get to the inner workings of the door (I think).
Does anyone have any suggestions? I'm a novice at car restorations so I'm hoping someone with more experience will have a trick or two I can try.
