Door won't lock, (power locks) Options

[HectortheRican]

I went to lock my doors today and the pass. door refused to lock. I would physically move the lock tab, but I could tell there was resistance somewhere down the line in the mechanism. Took the panel off and started checking. Key tunnel turns freely and the pivot that connects the inner handle's lock tab with the rod leading to the door jamb door jamb is fine. I'm assuming this has to do with the door jamb unit itself because the blockage/resistance is somewhere in there.

So before I start taking the door jamb and things apart tomorrow morning, has anyone experienced this or know exactly what's going on? Thanks.
