I have a 69 Camaro and cannot get the passenger door open. Outside button and inside door latch and lock all appear to be operating correctly. Doesn't feel like it's releasing the lock. Is there any way you can still a pick or something on the inside of the door latch to release. Any other suggestions would be great. Have tried pushing in releasing pressure off of the door pin, screwdriver to release buttons further, spayed with WD40. Still won't open.

 

Might be that the rods are disconnected. Try to look into the door cavity with a light while the window is down. I would pull the inner panel off the door and then you will have access into the door inner cavity to see the latch.

 

wow sounds like mine when we tore her apart. You can do what we did and just beat the hell out of the door until it opens.......lol
