Water under left rear seat carpet

[tomcat14623]

'03 C2 coupe

Spent a long time reading through all of the related topics on this and narrowed it down to 1 thing - water drainage: sliding roof, rear.

Info:

Just realized after a couple weeks of heavy rain, the carpet started to smell a bit strange. Discovered the right rear seat was all wet (carpet).

I found the drainage diagram here for Coupes and think the drain labeled as "1. water drainage: sliding roof, rear" is the problem. However, from the diagram, I dont understand how I could access the drain outlet by the right rear wheel ? It looks like it is above the rear wheel sort of in the engin compartment? Are there any real photos or instruction on how to get to it with comprassed air ?

Also, is it possible that the outlet is NOT clogged, rather, there is a cracked drain tube behind the right rear seat that is casuing the leak ? If so, how would I begin to replace that ?

I do have CPO on this car, do you know if this is covered ? ie. the carpet drying and rear drain tube replacement cost ?

Thanks a bunch for all your help.

I think a great place to start would be to have a friend sit in the seat while you hit the car with the hose. Eventually they should be able to pinpoint the location of the leak.

I'm not familiar with the 996 drains, but here's a photo that will show you that it certainly is possible for a cracked drain tube or a small hole to appear, with no provocation:

This photo was originally posted by Stefan, when he found a hole in one of his Boxster's drain tubes.

Most part of the sun/sliding leaks be caused by the rear connection/attach of the drain system on the roof unit it self, You have to lower the rear part of the roof trim to check this out.

I searched everywhere but could not find it.

Also, I had a typo on the title of this problem. The water leak was under the left rear seat behind the driver seat and not the right.

Have you checked the sunroof drains?

Thanks Loren for fixing the title.

I've read all of the drain related topics and know that the sunroof drain is the problem. I see from the diagram you posted where the sunroof drain is (rear drain behind the left rear wheel). But I dont know how to get to it in my car ? Cuz from the diagram, it looks like it is behind the rear fender so I have to remove that ?

1) do i need to remove the left rear wheel and also the wheel liner in order to see the drain outlet ? or is there an access from the engin compartment ? or remove the rear fender ?

2) How do I remove the interior pillers to check the upper and middle part of the rear drainage tube ie. the connection points ?

3) How do I remove the carpets (under the back seat) for the clean up ?

Thank you.
