2010 Yukon XL - Roof Leak | Wet Headliner

[BetMic2025]

Help! Something in my truck is leaking. After a rain the passenger side headliner and seatbelt are soaked. I've checked the sunroof drains an they seem clear. It's never been wrecked or anything that would cause the problem. I don't know what else to check. Anyone have any ideas.

Roof rack maybe?

Sunroof, sunroof drains, the antenna and your roof rack inserts.

The most likely culprits are your antenna or right rear drain. Put some clear RTV around your antenna and then test it. Blow out the drains with a can of air. Make sure the area underneath the glass is free of dirt and debris.
