My drivers side floorboard is wet. I have read all the posts on this forum about possible reasons for my leak, but the question I have was not answered.

Can a loose PASSENGER side corner marker light cause my drivers side floor board to be wet? My boyfriend replaced all my roof markers recently and the passenger side corner marker was not attached as it should be and had condensation in it. Thanks for all your help!

 

I kinda had the same problem. But it was in the middle and the overhead consloe would fill with water, then everytime I stepped on the gas it would pour out all over. I have two friends at work with H2's as well with the same problem. We all put a little bead of clear silicone around our lights and it fixed the problem. When you need to replaec a bulb you can take a razor and cut the silicone back off. but that was the easiest thing and worked for our 3 trucks.

If you fix this you have a dry hummer ...

 

I had water leaking in mine too on both sides where the handles are by windshield and under drivers side floor mat. Both side marker list needed to be resealed.
