When using either the door switch or the remote, the two rear doors will not lock. However, if you lock them manually, they will unlock using either the door switch or the remote.
Do you
have the same problem?

Ok looking over the wiring diagram I see that the rear doors have their own lock and unlock relay. So I would check the lock relay for the rear doors. It is located in the rear fuse block under the left (drivers side) rear seat. It is relay number 18. If you have a multi meter or test light you can check it. Simply back probe the gray wires that go the locks (the gray wires are the lock side) hit the lock on the switch and see if you get power. If you don't get power then the relay is bad just replace it and it should work again. Thanks and let me know how it goes.
