Thread: Leaky sunroof

The first thing to check is that the drain pipes aren't blocked, then go and check the seals on the roof itself. The best fix usually depends on the cause, of course, replacing damaged seals, remove debris accumulated in and around the rails and flush the drain pipes.

Thanks for the advice, I have looked at the offending sunroof, but am unable to see the drain pipes. Are they the tubes at the front of the rails? If so, what is the best method of cleaning them out?
All the seals look good, and the rails look clean. I think I'll clean them out properly and re-grease them though.
Cheers,

I'm going through my own sunroof dramas right now but mine is an aftermarket Hollandia 300 sunroof where as yours is probably the factory Land Rover one. From all I've read it's usually about cleaning the drain pipes and something silly like a gumnut blocking them up. I don't have drain pipes on my sunroof (it's all sealed from the outside apparently) but from what I've read people get compressed air and give the drain pipes a blast either from the roof end or maybe even from underneath the car if you can find the outlet end of the pipe you can blast compressed air up and whatever is blocking it should come out through the roof pipe...probably heard more about people blasting air into the roof pipes though.

After reading everything it really baffles me why these cars have sunroofs at all...much more trouble than they're worth.

Because it has been leaking though I'd be inclined to pull up the carpets and just do a quick check to make sure they haven't leaked previously without you knowing and there isn't water trapped under the underlay. Under the carpets is this sponge underlay sound deadener stuff which soaks water up really well and it has a layer of rubber on top of it which means once the water gets in there it can't go anywhere else and you won't even know it's there till it eats through your floor.

As soon as I realised my roof was leaking I checked under all the floors and found rust in the front two floor wells...luckily only surface though so I cleaned it up and now it should be all good.

This all well and good, but, I see no openings in ANY tubes to put compressed air. My sun rooves are factory. As far as the rest goes, within the next Month or so I will be Pulling the old girl off the road for a new motor and complete interior.

The drains for the rear sunroof window exit behind the tail lights or close enough to there. They start at the front of the sunroof unit - one goes left, the other right. They travel along the top rail and then drop down in the left and right rear pillar cavity to drain. Usually they get dirt and spiders - I guess in Aussie - maybe a snake or two ;-} Although my drains were not blocked the fitting that the pipes plug into on the sunroof frame had sealant that had lost its sealant properties...... I was lucky I guess, as I was stripping the headlining out to repair the saggy stuff so getting to every thing was easy. I pulled the frames off the body, cleaned and resealed the lot. fixed the attachments and blew the drains out. Just rembered - make sure the the drain pipes don't have any crinks or compressions in them. One of mine did - probably ever since it was manufactured. Good luck.
By the way if you have a sagging head lining - I removed the panel, stripped the cloth, cleaned the panel 'gently' with a brass wire brush to get the old glue stuff off and roller painted it. Looks amazing and I will never have to worry about saggy lining again. Cheers
