Can't open door...Help

Agree, it looks good. I’m thinking the lock is somehow not disengaging. I’ve had that before with a Mustang. I’d have to move the lock knob up and down several times then it would release and voila, the door would open.

Yup! That's what I'm thinking. It has something to do with the door lock function of the latch. It looks in too good condition to be a corrosion problem.
