2012 Yukon SLT New and need help! Drivers side leak.

[KurrieredesTodes]

Hello, I have been searching the forums for a while, and I have tried all of the suggestions that I seen. I have a leak that is coming in and down the column A wiring and to the floorboard. It seems to only do it when I am faced downhill. I cleaned the channels, cleaned the drain holes, even had the windshield removed resealed and replaced. I have soaked the sharkfin, the roof rack channels , and the door seals. Only when I let the water run over the top of the windshield was I getting the leak when parked downhill.

Here is a picture and video of what I have when I removed the headliner to find the issue before I replaced the windshield.

Open to any other suggestions.

The shark fin on the roof is leaking. You can get a new seal and use a little rtv around the hole.

Thank you Big Mamma,

I ordered a new shark fin, added rtv around the hole, waited a few hours for the rtv to cure before doing a water test. it seemed like it worked.

last night we had a storm, and this morning more water in the drives side floor pan and the foam is saturated. I pulled the A column and there is no water sitting inside that it rolled down from the top.

I'm so frustrated with this!

anyone else have any ideas.

I’m sorry that didn’t fix it but I’m surprised. if you have a sunroof check around it sometime you’ll see leaks on the headliner but not usually. there are lots of YouTube videos on it. If that’s all good next is the windshield. Pull the A pillar cover and have someone outside spray with a nozzle, preferably from above. Last is in the cowl area there’s a drain that can get clogged up. YouTube video once again.

I had a constant leak on the driver side floor bed before I narrowed it down. When you open the driver door make sure the tubing on both ends with the wires inside are flushed into the frame of the door and the opposite side as well.

Here's the fix to your problem.

Bottom line: there's a hole in the weld seam. You can fix it using 3M Windo-Weld. That's what I used to fix the issue.

You need to make sure you put it in the right place. Look at my last post in the thread for detailed pictures.
