I have a very frustrating problem with my 1992 Rover 820 Saloon Central Locking. I am unable to lock the car from the passenger door and I cant figure out why that should be. I have replaced the 2 mini micro switches in the latch motor in the pasenger door and also the micro switch on the passenger door, which triggers the lock motors.
I only have a key for this car, no infra red fob. Turning the key in the drivers door locks and unlocks all 4 doors. Sitting in the car, I can push the drivers door lock button down and all 4 doors lock. Raising the drivers button unlocks all the doors. It is impossible to lift the passenger door button or to push it down. This is what I cant figure out. If it was a mechanical problem with the mechanism, I would not expect to see the button go up or down.
I wonder if anyone can point me in the right direction to solve this problem.
