Replacing sunroof seal

[ukrkoz]

Ok, I have to replace sunroof glass seal.
I have the seal, OEM GM product.
I know how to remove the glass.
Question is - exactly how do I reinstall the new seal? Is it glued on? It does not look like something that will crimp on by itself or, seal tight just from tension.
Also, I start seeing some horror stories about secondary seal embedded into the glass and preventing the new seal from sealing tight.
Any recommendations? Job planned for tomorrow, don't want to get cought with unsealed sunroof, it's back to daily rains here.
Thank you

The old seal should pull off rather easily. It should not be glued on.

It is designed to pinch the glass. Use some spray silicone to help it slide into the glass.

I had to replace it on my 2008 Yukon.

When you put the glass. Back in, make sure the front edge is flush or slightly below the roof line and the rear is flush or slightly above the roof line. I let the new seal center the glass in the opening.

Is your sunroof leaking? I have bunch of sunroof parts. I rebuilt mine from a couple others.

Well, I was driving about 2 weeks ago, in rain, took turn and found water dripping down onto my right thigh. From the map lights cover. Looked at the sunroof at home, and about 5 inches of the glass seal were pealed off the glass, on the edge, in the rear. Tilted sunroof and found that seal, in that area, completely came off the glass.
Just for clarification, all drains are clean, I checked.
Thank you, wjburken. So it's just tension seal....
I'll remove the glass completely, says to simply undo 2 bolts and take it out. Should be much easier to do it on the table, than on the car.
I'll report back how it went.

OK, here we go:
1. tilt sunroof ajar
2. you will see 2 accordion like dust dams on either side of the opening. Pull them off. Very easy. grab on the side, pull.
3. this will expose 2 per side #25 Torx glass mounting screws.

Don't repeat my mistake, Have silver marker handy and mark brackets on the guides positions. This will save you undoing screws several time slater, for glass alignment
4. Remove screws, making sure you do not drop them into the sunroof frame. Pull glass out. Not heavy. Tahoe hood makes excellent work table for the project


5. Rear of the glass is where the markings are. Also, just in case, glass has 2 plastic "combs" on each side, taller end is towards the rear:




6. Remove the old seal. Pulls off very easy. Scrape and dirt/sealant/etc with blade off the seal mating edge.




8. OK, so there is a composite seal in the glass. If it's torn torn, tough shit, you have to replace entire glass. Otherwise, clean sealing channel in that seal thouroughly. I used denatured alcohol, rag and toothbrush. You can see, how much dirt comes out



OK, I can attach only 5 files, so I'll start another thread and then repost it here.

Sunroof seal replacement part 2

Unfortunately, I have early signs of the glass permanent seal chipped off. No idea how: Start applying new seal from the glass outside. Silicone spray helps to slide it over the mating edge. Now, you can see how the new seal does not completely overlap the glass, as it should: So flip...

thank you for the diy

Step 6. I don't understand what it is that you are scraping off.

Edit. I just replaced mine. There should be nothing to scrape off. If there is, then someone put some glue or seal on there and already did a repair on it.
