Hi! I am hummer H2 SUT 2008(v6.2) owner from Russia. Have problem with heating/ajustment front seats(can't switch ON last couple days. Hope it is just fuse, but no idea - were it is located). Thank you in advavce, Yury! It is too cold here last days(-20 C) .

SOURCE: both front heated seats not working

Page 43 in the document linked to below is a wiring diagram of the heated seats in an 850. If you're lucky some wires have come loose and are hanging under the seats, if you're unlucky you might have to do some shredding of the seats in order to replace broken parts. If so there is a fairly inexpensive repair kit made specifically for this purpose, but I don't have the part number available right now. Arm yourself with a multimeter and get to it!

Good luck!

The fog lights run by default during the day in the "auto" position. To activate the headlights and the fog lights you need modify the jumper position in the fuse box for the lights. "see fuse box diagram"

Seal all the lights on top. Mine flooded from the water running down the light harness wires. Used clear rtv sealant and fixed it. You will have to remove the seal the two larger lights on the corners.

SOURCE: I need to remove the luggage racks from my 2007 Hummer h2 SUT

I have the same vehicle and was able to remove mine with the following steps: 1) remove light behind each rear of luggage rack rail using phillips screwdriver (one screw each side). 2) remove molding underneath each light using T20 torx driver (2 screws each side). 3) Loosen cross rails nobs. 4) Side cross rails off of roof.
