Drivers Door Stuck

1994 Lumina APV. Drivers exterior door handle broke. I replaced it and it worked great. Then it would not open from inside or outside. I looked in with a flashlight and all the linkage is moving but the latch won't disengage. Any help appreciated.

...since it worked previously, there might be a slight position error of one component relative with the other so that it might need just a little extra travel....it this is the case did you try pressing against the door to release tension on the latch while you pull handle at same time...sometimes it works.

Door suddenly started working. Thanks. I think the door was actuallly locked even though the button was up, the key position was sllightly off.
