Headliner is soaking wet! Where's the leak?

[Mighty Hd]

08 Tahoe Z71 3LT 4x4. 600 miles on the clock.

I washed the vehicle today, used the aircompressor with a tip on the hose to blow the excess water off the paint. As I was wiping down the door jambs I noticed in the rear the headliner was soaked.

It's on the right side, between the right liftgate hinge and the edge. I can't tell where it came from---I pulled down the rear headliner trim & weather strips.

Has anyone else had this problem?????????

Thanks guys.

Mine leaks from the exact same spot...I ran it for a few months with the interior trim panels removed so I could trace it. The water is entering around the rubber grommet where all the electrical wiring runs from the truck body to the hatch...on the truck side. It is just a really poor grommet design and really does not seal well at all.

Warranty time! Pay the dealership a visit!

Check your sunroof. My girl left my sunroof open in my old denali, but she had the shade slider shut. I was going up a hill one day and a crap load of water spilt out all my rear vents in the headliner. I was like WTF, opened the sunroof shade slider, and the sunroof was barely cracked. I was pretty mad. My car smelt like wet dog and mold forever, nasty.

No sunroof on this vehicle.

I removed the grommet and put a tad bit of silicone on the grommet and reinstalled. We'll see how it turns out.

EXACT same problem here. I also found it to be the electrical grommet which I securely taped down, silicon sounds like an even better idea though.
