Please can anyone help. I have recently bought a 1999 fourtrak TDX, the central locking works the two front doors but not the rear door. I had a 1995 foutrak and the central locking worked all 3 doors which was a lot more convinient. Does anyone know if this has been changed on purpose or I may have a fault on the rear door. I have looked in both manuals as i still have the 1995 model and it doesn't say it should or should not work the rear door. Thanks, any response appreciated.
