On the rear passenger door, behind the driver's seat, the power lock control from the driver seat and from my remote fob activates the lock just fine.

However, a passenger sitting in that seat, you can't unlock the lock. I suspect it is some child lock mechanism. For the life of me I don't see a lever anywhere though. The manual describes a child safety lock and that some Burbs have it.

Where is the darn switch if it isn't on the door itself? Usually I expect it on the door edge. Or is there something internally wrong with the lock?

Thanks
