Leak in roof

[theador]

After the heavy rain I saw a puddle of water on the boot floor protector on the left side close to the boot subwoofer location (as you look into the boot). Feeling around, it's damp on the headlining in the left corner directly above (where the plastic trim meets the material lining. I'm assuming the water is coming through where the roof rails are screwed in. It's only happening on one side, that may be because I generally park on the left hand side of the road though. Anybody had this or know a quick fix?

Do you have a sunroof? If so, one of the drains may be blocked or disconnected.

[theador]

Hi yes I've got the sunroof. Is that an easy thing to check?

[Greenmamba]

Sunroofs usually have 2 drains, 2 each side, one going forward down the A post and discharging behind the front wheel; the back drain goes down the C post and probably (not sure about Fozzies) through the area around the subwoofer and then out via a little flap underneath the car behind the back wheel. When you've got the SR open, trickling a little water into the gully on the "faulty" side should result in that water either a) soaking the headliner or b) dripping onto the ground behind the back wheel. if it doesn't emerge onto the ground, it's probably the leak. To access the pipe, the headliner will have to come down between the B and C post for inspection. The drain may be either blocked, in which case clearance may be by air hose/wire/sucking/whatever; if it's not blocked, there's likely a break somewhere obscure and inspecting behind the headliner is called for.

Thanks GreenMamba. I'll give it a go when I get home.

[Greenmamba]

No worries. I just noticed - I said the C post, should read D post (the one by the tailgate).

[theador]

Ah yes. So, pull it down from B to D?

[theador]

Ah yes. So, pull it down from B to D? I wonder if some one-shot drain unblocker would clear it.

[Greenmamba]

The drain could have come adrift from where it connects to the sunroof, so from B to D would be about right. First, though is to establish that the drain is in fact the cause of the water ingress!

I think I may have got lucky. The left hand boot for the wiring into the deck lid had come loose. Hopefully this is the source
