Passenger Door Doesnt Lock...

Recommended Posts

Hey guys,

I have been an owner of my 99es300 for all of 3 days now, and today I noticed my first problem. The drivers side passenger door will not lock. I tried locking the door with the key as well as from the inside, and it wont secure.

I have done some research on the board and see that some of you had issues with the door opening from the outside but able to lock from inside. I cant securely lock mine at all.

Should I reach out to dealer to get an idea on fixing?

Chances are that the actuator rod from the lock to the the actual locking mechanism has come off the locking mechanism. Its held on with a plastic clip, which may have broken, or simply come undone and fallen into the bottom of the door.

Regardless, the only way to know for sure and then make a repair is to remove the inner door panel and the plastic weather shield and take look. Been there, done that, not a lot of room, not a lot of fun, but doable for a DIYer with some patience. Good Luck!
