My passenger door latch has been sticking in the locked position again lately, and it's not been possible to lubricate my way out of the problem. Accordingly, I ordered a new mechanism and it came today. Door trim off, and it'll go in in a matter of minutes I thought. No such luck. I discovered I'd have to take the window winder mechanism out, and probably should have taken the window out too, but in the event I held it up with one hand while I bent the runner out of the way and got the latch mechanism swapped over. So far so good - the new one seems to be working, locking and unlocking freely.
