I have replaced the latch and the actuator (brand new, OEM from Honda). I did this because as the problem got worse and worse, it eventually clicked the latch into a spot where the door would not close and it was obviously not supposed to be (and I couldn’t get it to rotate back into place… trust me, I tried).
After a day of having it all in there, the problem seems to have gotten much better. Now the only problem is that I can’t open it from the outside. From the inside, I can pull the lock knob up and open the door at the same time. However, this same maneuver doesn’t work from the outside. It seems like the lock is simply not moving all the way into the “unlocked” position. I say this because if I hit the unlock button, it will click up then immediately back down, locking all of the doors.
Could this be solved simply by cleaning the outside door latch, or is this more likely to be that the lever is not in the right position?
Also: thank you all for your help.
