The lock motor is silent. I may have to obtain a schematic to be able to test for power to the motor. I am assuming that when the key is used in that door it is mechanically moving the mechanism and not electrically. Thank you for your thoughts on this.

I can only open 3 doors when using either the interior switches or by using the key on the driver's side. The passenger front door lock will not operate unless I use the key in that door. I can lock or unlock all 4 from that point. I wonder if anyone has seen this? I have attempted to remove the door panel to have a look. This proved to be very difficult when it came to removing the cup around the inteior door latch mechanism. Any help here would be appreciated.

I have just recently purchased this unit and have to install car seats for my children. I looked high and low for tether anchor points. Can anyone tell me how I should proceed?
