My passenger door lock isn't doing anything. It seems to make a squeeling noise, and it wiggles a bit but it wont lock/unlock.

 

My passenger door lock also intermittently makes the noise. It reminds me of the sound of stripped nylon gears. I know eventually I will need to replace something, but I haven't torn into it to find out what, yet.

 

anyone find out anything on this yet? I have the same issues... makes motor noise but no longer operates.
