doing this repair- my motor is actually fine. I cleaned it out, and it operates strong.
The issue was a cracked lever arm. Split down the side so it slips, instead of pulling the lock mech when the gear wheel rotates.
you can see the crack all the way down the barrel
The plastic lever arm slides down onto this knurled post- pressure fit.
I roughed up the plastic, drilled some divits into the outer diameter to give jb weld something to grab as well as in the crack.
Ideally a flat, metal collar on the outside would be ideal, but I couldnt find anything.
Ziptie, etc won't work as there is no clearance with the cover.
Hopefully this holds and will probably add some epoxy inside the hole/on the post, when I push the lever arm onto the post,
to help keep it locked in position.
The youtube vid from
@Texasknowhow is excellent in how to take everything apart- really made it easy.
I'm thinking that maybe years of accidentally pulling the door handle at the same time as power unlocking/locking may be the cause.
of breaking the arm.
