Replacing door actuator on ml500. How do I remove the outside door handle?
Find your fusebox and see if you can find the fuse for the auto door lock mechanism. Just pull the fuse out and it should take care of the problem.
drill the lock and push in, lift open the trunk door
make sure the trunk is unlocked - then just push on the forward end of the cover door and it should tilt open. The trunk lock will also lock the fuel door.
