Lock Question

Greetings all,

I"m working with my '93 ZJ and have had the front passenger door panel off for some time. Eventually the power lock seemed to struggle to lock and after a press or two via the key fob, it would eventually lock. Now it would appear that the motor doesn't have enough power to lock the door (hoping I didn't fry it with a thousand attempts each time I locked all the other doors). When manually locking the door it would seem that more force is required to move it than should be required. All the other locks work fine. I have since disconnected it in an attempt to spare the motor if it isn't already dead. From what I've read on the forum it is quite possible that I need to lubricate the lock itself.

Would anyone have some insight as to how the door lock is removed from the door, I'm not entirely clear as to what it is I'd be lubricating once the lock is removed. (if it has to be, was really hoping to avoid that)

Thanks for your time!

The lock & the latch are one mechanism. This is going from memory, so I hope I don't forget anything. To remove
- Disconnect the electrical plug.
- Disconnect the 2 visible actuator rods at the lock end by snapping the plastic clip off the rod and pulling the rod out of the hole.
- Remove the 3 torx bolts holding the whole mechanism in from the rear edge of the door.
- Remove the remaining 2 actuator rods that are around the back side of the mechanism.

I took mine apart down to the plastic housing, cleaned all of the old sticky grease off, lubed with fresh grease and re-installed. I did not take the plastic housing apart. It's a pretty complex mechanism. so I would suggest photos as you take it apart. I got mine back together without them, but it would have been a lot easier with something to reference.

It didn't help though. I ended up with one from the pick-a-part for about $20-$25. It was gunked up even worse than mine, but worked fine when I cleaned it up.
