D16y7----- keyfob opens/locks driver's door only. I can hear a mechanical click in the passenger door...the tab from the inside flickers but does not move to the lock position.
One can unlock/lock the door with a key and using the inside tab on the door.

Has anyone experienced it before?...any guesses?

 

Take off the door panel. There is a pivot point where 2 metal rods connect the locking motor and the front lock tab. Either it is rusty and stuck, or the motor is bad and not powerful enough to rotate the pivoting point. Try cleaning and lubing the assembly and if that doesn't work its time for a new door lock motor.

 

Thanks.
