I have a 1999 ML 430. When you unlock the car with the remote all locks open but you cannot open the rear passenger door from the outside. It does open from the inside and once you do this, the door will open from the outside. Any ideas or solutions? Please help

The ML has had a lot of problems with their lock mechanisms. You have checked the child safety lock, right?

I've checked the child lock. Anyone the child lock should prevent the door from opening from the inside not out.

Duh. Please disregard my previous mentally challenged statements.
