My passenger side door hasn't been closing well lately, so I tried having a look at it. I was comparing the other latches, and I somehow locked the latch closed. It won't let me close the door. What do I need to do? Yes, the door is locked locked and open at the same time.

 

Just a reach here, as close as I can get to yours is my 95. If the door is unlocked, while pulling the handle (like opening the door), take a screwdriver or something and see if you can move the latch that hits the stirker on the door pillar to where it is/thinks it is open.

 

Spray some WD-40 in there. Use a screwdriver to force the latch up and see if that fixes the problem.

 

I'll go with poorman's idea. Use a big screwdriver or something. As you hold the handle open, swing the latching fork outwards. It doesn't spring by itself.

If that doesn't make sense, go to another door to look at that fork in the open position.
