I just recently bought a 02 Disco. I am the second owner, and I am experienceing locking problems. The passenger front is the only lock that fully functions correctly. It locks and unlocks with the FOB and the interior mechanism as it should. All of the other locks will lock using the FOB when pressed for a second time, but none of them will unlock at all. I can hear the actuators attemping to move the locks, but no results. Please help. I have checked the fuses that I am fimiliar with, but I am lost. Any advice or suggestions? Thanks!
