Water leak

[byrds6]

It has been raining most of the day. When I left work today though water poured from the little oval section in the driver's side A pillar. Anyone know what would cause this? I looked at the door weather stripping and it looks fine and wasnt wet. The windshield was replaced about a year and a half ago so it should be good too. Never had an issue until today.

I had a leak that come through the mastic in the firewall Improperly applied at factory they said. This was a 2013 Yukon slt. Nothing appeared high up. Just got the carpet wet. Do you see water from the a pillar itself?

No sunroof to check.
Only say it come from the oval near the top of the A pillar. Nothing in the floor or anywhere else and it only poured out a moment then didnt do it again.

XM antenna gasket ?

Not sure. There is a small space in the back side of it but not sure if it's supposed to be. None of the headliner is wet though. 8d think if water came in there other parts below it would be wet before it ran 10inches across then down the pillar

I share that thought. There is a seam in gasket at the back. A pillar cover comes off fast Won't take long to figure out from there. Couple pitchers of water poured in different spots starting at lowest possible and working up and u should have it pinned down

How does the pillar come off?

How does the pillar come off?

The oval pops out. Then a 3/8" 10mm 12mm. (Don't remember exactly ). Hex head bolt/screw The rest of the cover snaps in

No other parts to take off or anything
