Land Rover Repair: Freelander Remote Locking, electric actuators, back doors

Question
Hi
We are having a problem with the opening of all four doors with remote locking.  The driver's side front and back doors won't open unless the key is used to unlock, and the back door won't unlock at all unless from the inside.  The car will lock fine with remote locking.  Any ideas?
Many thanks

Answer
The door latches (which contain the electric actuators) are probably bad in the dors that are malfunctioning.  To verify that visit a workshop with an Autologic or T4 Land Rover test system.  They can actuate the power locks one at a time to verify the signals are right and see what they do.
