The wipers move when you wash your screen with your headlights on every 4th or 5th wash and they can fail to park fully which is what drains the battery. They also fail internally as they are full of electronics. I’m not sure they have a separate fuse as mine were unplugged when I bought mine. Have you connected up an ammeter in series (earth strap removed) and identified a drain with the car locked and asleep? As already mentioned the FSR hedgehog is another culprit and there are several HEVAC fuses

It doesn't sound like the main fan as its very quite and is dead central behind the control panel and what Ive read is there's a small cooling fan behind there. I pulled fuse 12 (air con) out and it has stopped the noise and the drain has either stopped or slowed down loads. The next couple of days will tell if the battery dies but so far so good.

From what I can gather from this forum, any rangerover made in the past ten years or so will suffer a flat battery if it's left unused for a couple of weeks. Their owners are a special breed of people who deserve the utmost respect and pity.
