My 06 Fabia has been into the dealer to get a leak fixed twice now, but it is still leaking in the same place the rear nearside foot well, the dealer claims to have replaced the seals behind the door cards twice but clearly he is looking in the wrong place, the leak is definitely nothing to do with the windscreen washer but has anybody any idea where to look? The car is still under warranty but my local dealer is getting nowhere and I want it fixed. Thanks for any pointers.

The leaks come from between the carriers and the door:

Easy way to check its been done would be to have a look lots of guides on here on how to do it yourself... did all 4 of mine in about 1-2 hours for about £4.99 remember to buy some spare trim clips from a stealers first
