Ok, I removed the inner door skin. Everything was connected. I kept trying to get it to open up. And, finally it did once. With the door open, I locked and then unlocked the door and again the latch would not open. Luckily on my parts car, I removed and installed the latch from it. Now the door works like it is supposed to. From looking at the original latch mechanism, I couldn't tell what is wrong with it.
