Bad Seal Around Sunroof?

[DC_Roller]

Anyone else have problems with their sunroof leaking? The last two rainstorms, when I pull out I have had a stream of water hit my head. Is this a common problem?

I'm new to Hummer but already have heard this issue. All of these damn sunroofs have drain tubes, even the admiral's Subi has them. Open the thing and you will see two in the front, clean them out. I have yet to find the rear two but will locate when I really have a leak, which I don't at this time. I did run water in the channel to ensure they were wide open, they drain behind the front tires.

Thanks bro, I will check it out.

Having the same problem lately with my '07. It sits outside under the trees here at the house during the hot Texas summer.

The gasket allows some water through and the water should drain. My problem was that the water wasn't draining from the sunroof water collection tray. After a rain, open your sunroof and see if you have water standing across the front.

I went to the local aquarium fish pet store and bought some plastic tubing, small enough to run down into the drain holes. I put a soapy water mix into the collection tray hoping it would help cut the grease and debris that was blocking the drain. I was able to insert the tube quite a ways and then blew blew into the tube to help break up the blockage. I had it fixed, but the latest rain, it backed up again. Probably need to do it again till I get all the crud flushed out.

If that tubing is fairly stiff, hook a battery operated drill on it and let it spin inside the drain tube while the water is flushing. that will clean it out.

My sunroof drain tubes (the 2 front ones primarily) get clogged every 6-12 months. I use a weedwhacker cord pushed into them. My driver's side one is currently being a pain and won't unclog.

I might have to try the SPUDS technique or use an air hose.

Anyone else have any other successful techniques?
