My newly acquired 04 LS430 with Smart Access has a problem with the front passenger door lock that I do not believe is an actuator problem. All switches and buttons make it lock and unlock except when I'm in front of the passenger door and grab the handle and pull, nothing happens except for a goofy feeling I get like I'm trying to break into someone elses's car. I can open the door by grabbing the back door handle, but then nothing happens when the lock button on the handle is pushed.

Is there a separate switch for the handle that controls the grab sensor and lock button that might be disconnected? Is it an easy find? Is there a chart someone can post that shows where it might be disconnected? Thank you.
