How I fixed Sunroof & Overhead water leaks (NOT a plugged drain tube).

I had started this in another thread ~1 month ago, which had grew in size since then. I wanted this thread to have the correct title, and have the problem and solution in the first message.

The water leak I had would happen even in a light rain, and with the truck parked. Before I even moved the truck, I would notice a wet spot on the headliner above my (driver) head, about a half an inch round. Sometimes, after I back the truck up or turn out of the parking spot I am in, a few drips would come from the Overhead grill openings. Just a few drops, and then nothing (still, very embarrassing when you have company). I tried the drain tubes, and they seemed fine (lot's of threads here on drain tubes, so I will spare you the diagnostic details).
So one time, shortly after the rain stopped, I went out and looked inside the sunroof (before moving the truck) and here is what I found. I will leave you with the three pictures below, since one picture is worth a thousand words (especially when the picture has words on it ).

I hope this helps someone else fix their leaky sunroof / Overhead.

well it is crazy you posted this on the same day I figured the exact same thing out!!!

I had pulled the headliner down just a tad on the drivers side and found the same evidence, but mine was not leaking as bad

great pics and post - we are having a pretty hard rain here in KY tonight/tomorrow so the "voy" sits in the garage drying out - will repair tomorrow STICKY THIS!!!

PS - I can get some other pics of the wire harness inside the headliner while the drivers side is still pulled apart let me know if it is worth posting some pics

thanks again for posting this

It's a good thing you caught the leak before it turned into the mess that mine was.

I do not have a garage, so the truck had Green masking tape around the sunroof and the windshield for two days until I made sure the silicone dried up well. So far I fixed three water leaks: Roof rail, rear right corner; windshield, upper left corner; and the sunroof tracks. My truck should be the poster child (or truck ) for water management. I didn't mind the tape. The least I could do for GM after all the trouble I went through to fix the water issues is drive around publicizing the fact their product leaked from pretty much everywhere

Sure, the more pictures the merrier. I should have taken one myself while my headliner was down. I don't know why I did not.

Hopefully this fixes your truck too. Mine is still leak-free since I fixed it in December.

Thumbs up Leaking Roof 02 Envoy

Thanks for that info as it is exactly what happened to my 02 Envoy. The water is finding its way into the overhead control panel and dripping onto the rear view mirror. Thanks to your pictures I could trace the dampness back to the source and now have to get some of that good black silicone sealer.

Living out here here on The Wet Coast, a sealed auto is essential!!
