Question about 2004 Hummer H2
2004 hummer h2 leaks water from roof over front dashboard. sometine right side sometimes left, and sometimes middle.
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.

Like the first guy said. The small roof lights that run along the front edge of the roof leak water, usually during car washes or very heavy rain.the corners were my culprit. Clear silicone was the answer.
(Dont get it anywhere you dont want. use sparingly as it can be a pain to get completely off a nice paintjob)

Check for holes in the engine bay firewall, except for the ones with wires and cables going through.
