Hi - Drivers door is not latching - It unlocked just fine - If I unlock door I can hear the mechanism working.

The door latch is in the open position, I can push it all the way to close the door, but it's not locking onto the thingy.

I opened the door and again the latch is open, I closed the latch by hand all the way, and it won't lock down.,

I pulled fuse 33 and 34 hoping the blown and electrical issue.,.,but not thinking its not electrical,..,?

Ideas,.?
