. I took it to the dealer and they said they all leak and that is why they have that tray with the drains. Is that true? I had a H3 2006 with a sunroof that didn't leak and my daughter has a Jetta with a sunroof that doesn't leak .
What they meant by "they all leak" is that the sunroof seals around the glass are not meant to keep water from getting down in the sunroof, and tray and drains are there to drain the water that does get down in there. The problem most likely exists with your drainage tubes. They can either be clogged, or in my case with my 06 H3, the tubes were somehow disconnected and I had to drop down the roof panel to reconnect one.
The sunroof in my '06 H3 was leaking also. I changed my interior this summer and while doing it I was 4 drain tubes in each corner of the sunroof frame. I pulled each tube off and blew compressed air through it. It worked wonders...I have been through heavy rain and Hurricane Irene since doing that and I am still dry. If you don't have the tools to take your headliner down they are easy to find and relatively inexpensive. I hope this helps.

My 06 was leaking during rain also. It turned out to be the sunroof. There are two drain tubes in the front of the sunroof that run the water down the corners to the ground and two drain tubes that drain water out the back corners. The water would seep around the glass, which is expected, but both of the tubes on the front of mine were plugged, and the water would overflow behind the dash and fill my floorboards. If my H3 was leaning to the left during a storm then the drivers side would be full of water. If leaning right, then the passenger side. I had to open sunroof and blow compressed air into the drain holes to clear them, but be careful, too much air will separate tubes from sunroof and then you will have to remove the inside paneling around sunroof to get to tubes and reconnect. You may only have one side plugged. you can test it by opening sunroof and pour a little water in the small catch pan in the front of the sunroof and see if it drains as expected (to the ground under the firewall on left AND right side). You can see the holes in each corner of catch pan to drain the water. Plug one with your finger, then the other to find the plugged side. Good luck!! Hope this helps!!

I brought my 2006 H3 in to the dealer for the same thing. My blower stopped working all together but it started as an intermittent problem. He said he had to replaced a diode or resistor either behind the switch on the dash that controls the fan or on the fan motor itself. Have not had a problem since but that was only about 4 months ago.

If you look in the owner's manual it will explain this. Happened to me a bunch of times, really embarassing. It is an additional anti-theft device . If the computer senses that the key is inserted improperly, or that it is not a perfect match for the code it has in its memory for your key, it shuts of the gas supply to your engine for approx. 10 minutes to defer theft. Still happens to me intermittently. Now only very rarely. Total pain. I cleaned my key..carefully, with WD40 and after drying put just a touch of graphite on the key and started the beast a number of times. My dealer didn't read the manual either. You must wait the full ten minutes before trying to restart....otherwise it never totally resets and (the first time this happened to me) you can sit there and fight it forever.
I don't have my owner'smanual handy to refer you directly to the proper pages, but its in there under theft deterent. Hope this helps......and that Hummer can provide aneasy fix for this.
