I was very unlucky earlier this year and discovered my cowl drain where clogged and that water was comming in both through the air fan and the seal around the air fan
So took all the carpets out for a week to dry out (both in the sun and on the bathroom floor).
Jacked up the car and used a long pin with some paper and surfex hd and cleaned the cowl drains.
Then i flushed it from above with boiling water before i used some swissvax pneu and made the drains more smooth so dirt dont stick as easy (hopefully).
I discovered that one of the metal clips holding the drains against the chassie had come loos and was clogging the one drain. Any tips on how to attach it again?
Will be checking these drains more regulary (sunroof and AC to).
