I have a 2003 H2, 115K miles. I have placed RTV on the service marker lights and redone the door seals. Sunroof drains are fine and drain well. The issue I am having, after a huge rain, water basically showers you both driver and passenger sides from where the sunroof is, as well as running down the "A" pillar. Can anyone help me find this leak before it drives me insane?

I forgot to add, since the last huge rain, the "service airbag" is on after I have dried out the Hummer. What could cause this as well?

check your air bag module under the drivers seat for water damage or corrosion its bolted to the floor. as for the shower the drains can be disconnected at the sunroof if they "cleared your lines" with air.

 

Inspect the area above high as you can go.

 

The lines are clear, no air needed. Will check the module under the seat.

 

Recheck your sunroof channel, pour water into that channel and observe where the water exits.
