I’ve been battling with the drivers side door on my 280zx. It won’t open from the inside or the outside. After several hours of using various slim Jim’s and coat hangers I finally gave up that method after I was almost certain I was pulling on the right part. I finally (begrudgingly) cut through the interior door panel so I can see the internals of the door. I can physically pull on the rod that actuates the handle, and can physically move the lock mechanism up but the door still won’t open. I have no idea what my next steps should be. Any advise it greatly appreciated.
