So I think i've finally isolated the source for my floor mats getting soaking wet after big rains. After washing my car the other day I noticed water at the floor-mat again. Looked inside of the front passenger side window and behold it was wet in the corner inside the car... Pushing on the windshield from inside makes the water move back and forth in the crack. What do I do now? Is it just a matter of adding some silicon? Can't believe after all the checking of sunroof and a-pillar leaks that it ended up being this...!?
