GMPD:

Hello Dear Customer,

Unfortunately, it seems that GM does not offer the weather-strip separately from the window. I have included a screen shot from the licensed GM parts catalog show the sunroof and it's components.

Hello Kevin,

Unfortunately, the local glass shops are correct, and we cannot
help you, either. :-(

The problem is there are too many different sunroof seal
profiles, and not enough of any of them to make it worthwhile
for the aftermarket folks to make. It's a money-pit, with zero
chance of recovering the tooling costs. That is why you cannot
find your seal. Sorry. :-(

 

Well, I wanted to update this thread. I got sick of the wet seats and carpet, so I pulled off the sunroof seal today and inspected it. In the torn open spot, I injected RTV sealant and then smoothed the torn chunk back down. Let it dry and reinstalled it.

As if on que, it started raining just seconds after I finished. I waited about half an hour and went outside to see if it was leaking...stuck my head inside the truck and there was a LOT of water dripping past the seal, basically all around it every few inches.

This pissed me off worse so I pulled the truck into the garage and started tearing it apart. Took me a while to get that long, massive, heavy headliner out (it has the mid and 3rd row headliner air vents, etc.) but when I did, I found the problem.

At the back of the metal sunroof track assembly was a long thin strip of metal just laying there, slightly bent. When I saw it I knew what it was...part of the drain system. Come to find out, it is supposed to lay in the middle of the big sunroof frame, and catch the drips that come from the rear of the sunroof seal. Then divert that water to the side channels where it can run out.

At some point, possibly during my wreck previously mentioned, one of the plastic tabs that holds this metal channel in place broke and I guess it just flew back inside the headliner/frame and stayed there. This is why the leak became a problem after I got the truck back from the bodyshop after the wreck.

I went ahead and removed the entire sunroof assembly from the truck so I could re-engineer the channel back in place. For now I have used a ziptie instead of the broken clip, but I will move the sunroof around a few times once I install it in the truck before I put the headliner back in place, just to be sure my fix will work okay.

I also found one of the rear drains for the sunroof frame was clogged...quite possibly from glass fragments from the car I hit (glass was all inside the truck when I got it back). I blew it out with compressed air and made sure all 4 drains are clear.

Just thought I'd put this here for anyone with a GM SUV that had a similar problem. I am not 100% sure I have fixed it totally yet, but I've missed a damn good chance if not.

 

Hmmm, guess I should have mentioned that if the rear drain channel is completely dislodged you will get a flood also lol.

Glad that you figured out the problem...now get some baking soda in there so your truck doesn't smell musty and moldy

 

I actually pulled the entire front interior out (trim, seats, console, carpet). Pressurewashed the carpet and then vacuumed it, hung it upside down in the garage and used 2 kerosene heaters to dry it in 1 day, then reinstalled it. This was a bitch of a job due to all the wiring and electronics in my truck...fully rewired speakers, tv's in every seat, power inverter/ps2, satellite tv crap, etc.

And yeah, once I saw that metal piece back in the headliner I knew what it must be. When it is installed on the sunroof track, you can not even see it, which is why I didn't notice that it was missing.

It's rained for about 36 hours since I reinstalled it and not a drop back inside the truck.

However I did learn something...I had no idea that such a large volume of water was SUPPOSED to get past the sunroof seal. I thought, a few drips per hour would be the expected volume. Turns out it leaks about 100 drips per minute during heavy rain. Not in any particular spot, basically all the way around.

 

Cool deal man, glad that you got it fixed and learned something at the same time
