I haven't had my H3X long but the sunroof does not leak even after numerous power washes. My first choice would be the dealership under warranty. If they refuse, ask for a Hummer regional Rep look at it. My last resort would be for the compressed air.

 

i ma told its the REAR drains that are clogged. i have to take off my whole headliner to clean em! what???

 

how can i get the numbers and emails for someone to contact... like regional or something?

 

Your dealer can bring in a Service Rep if you ask for it. Your manual also has contact information.

 

i have 43000 miles on my H3 and my sunroof has never leaked

i love the sunroof, it is so huge !!!

Yea i love my sun roof too!! I haven't a leak yet!! (knock on wood)

 

I know this sounds pretty simple but on the rare occasion that I have had a dealer not want to take care of something I took it to another dealer and in every case they took care of it. I did the regional thing once and it worked like a charm. Regional Chevy guy told the dealership to fix everything on my list. ( It wasn't a Hummer )

 

I dont know if gm has this tool . but at the toyota dealer we are required to have a sunroof drain auger.. kinda like a plumber would have but its much smaller. its made by otc ill try to get a part number at work tomorrow. I wouldn't blow the drains out with air because the tubes will pop off and then you will have to remove the headliner anyway to reattach them. try a wire or the auger i mentioned.

 

Dealer fixed my 06 leak about 8,000 miles ago (under warranty) but did not tell me how. Now it is back to leaking again and I am beyond the max miles (now 43k). Thankfully I park mine in the garage at home. (btw, it is blue but not slate...lol) Sadly, if it rains at work I have to open the sunroof and soak up the excess water out of the channel before I drive home... Otherwise the water will spill onto the headliner and come out of the Onstar mic... not fun.

Looking down from a second story window the other day I happened to notice the rubber seal on the glass of the sunroof is shrinking and pulling away from one side. Would love to replace this to help solve this problem... Anyone know of a kit to replace seals and wear parts like this?
