This LRO reader emailed LRO.email@example.com seeking a solution to some sticky door locks on a P38 Range Rover.
The door locks on my 2001 Range Rover P38 chatter on and off when driving and I have to lock them manually. Can you help?
Morgan O’Malley, Diss, Norfolk
The most common cause of the fault you describe is with one of the three micro switches within one of the front door latch mechanisms (most usually on the driver’s side, because that’s obviously the door that sees the most use).
They often get stuck up with years of dirt and grime getting into the lock and contaminating the lightweight grease that’s in there.
The problem can often be cured by removing the latch from the door. Dismantle the mechanism (preferably somewhere clean, such as the kitchen table) and clean the whole lot out using WD-40 (or similar) to lubricate and clean it all, dry the components and reassemble using a very small amount of Vaseline to lubricate the parts.
