[Freelander 2: Rear door remote locking not working]

Hi

Freelander 2 GS manual Reg 2010

Remote locking has stopped working for just the rear off side passenger door, currently I am have to manually lock and unlock this door.

The central locking works fine for the rest of the other vehicles doors.

Any suggestions ?, is it likely to be a fuse and if so any pointers to changing /location etc...

Thanks in anticipation
