Unsticking a door

[HP2]

While I'm working on the front third of the car this winter, I wanted to get the door alignment set so I don't have to remove hinges after I paint the cowl. Not a big deal to do doors alone, but certainly tedious, and I finally got everything lined up where I wanted.

Problem occurred when I tried to open the passenger door afterwords. Lifting the outside release handle and I heard it click but the door didn't move. Since I had the windows down, started pulling on the door and it wouldn't budge. Checked the lock and it was unlocked. Cycled it to verify, yep, its unlocked. Pulled the release handle on the interior and no dice.  Grabbed a flashlight to shine it down the window slot to watch the mechanism and sure enough, the lock and both release handles are moving the levers in the latch. But the damn thing feels like it is locked in place and won't budge.

Suggestion on what to try next?

That's a tough one. I've seen it where although moving, the latch and/or the lock were not moving enough and putting it into a sort of stall. I read you saw the levers moving, but my question would be were they moving enough and fully. First thing I'd do would be to spray a good lubricant into the latch and keep working the lock and latch levers to see if you can regain full movement individually. Can you get a rod/lever into the door enough to manually push the latch lever and possibly trip to open the door? If you can, I'd pull the latch and soak it in degreaser, wash it out and re-grease it. I don't know if this'll work, but good luck nonetheless.
