Hey guys I hope everyone is doing well. This weekend I took apart my Scion tC 2007 due sunroof water leak coming from driver side front pillar and here is what I found. This kind of leak can happen on both front pillar more often than in the back pillars due to its design. I hope many people find it helpful.

 

Can someone re-post the YouTube video - it is no longer working. Thanks.

 

Jorge305 - can you please re-post the video? I too am experiencing water leaking from the A pillar and have been unable to locate drain holes or similar to address the issue. Thank you, in advance.

 

Did anyone here figure this out that could explain? I'm experiencing same issue

 

I am coming here looking up the same answers 3 years after the last post and thinking that the video is gone for good. I can not find anything on line to answer this question.
