C Pillar leak

[JBR14]

We recently took my daughters 17 Ecoboost into the dealer to get the camera recall done. They looked at it, said it needed a new harness and ordered one. Apparently they are on backorder. Today, is the first time it has rained and we noticed it leaking near the C pillar on the passenger side. I am pretty sure its unrelated, but does the camera harness run behind the plastic panel above the 1/4 window? I looked and there is a harness there, but I assume its not the harness they are replacing.

Thanks. After posting this, I just went and ran water over the roof. It is the 3rd brake light. Water is coming in where the clip that snaps in on the passenger side is located. I suppose it will be covered under the Ford ESP that I purchased. Just annoying.

Good to hear you found the source and post back an update once it's been repaired.
