My daughter has a 2004 mdx and the passenger door lock quit and I replaced the acutator and that fixed the issue for a few days. Then the door locks would not work with the remote but I could lock them with the switch but would have to manually lock the driver door. I changed the fuse which I had just done about a month ago and the remote now works the passenger door and the driver rear door but I still have to manually lock the driver door and the passenger rear door is locked and will not unlock with the remote, the switch or manually it wont budge. I would not think 3 actuators could go out at the same time but I guess it is possible. I had also looked up and seen that it could possibly be a multiplex integrated control unit. If it is the actuator any advice on how to get the rear passenger door panel off since the door will not unlock and I can not open it. Any input would be greatly appreciated so I could get this fixed for her. Thanks for any advice.
