The passenger side door will only unlock, so I took the door panel off and removed the lock assembly, found that the the plunger has a leak. has anyone had problems with this, and if so do you know where I can get one besides having to go to the dealership

 

Can you fix the leak? How hard can that be?
They will cost too much to waste one that is only half bad.

 

if it would lock I would just leave it. there is no way to fix it that I can see of

 

post a picture of it with an arrow pointing to where you suspect it is leaking.
