Soaked floor board

Thanks for all the history on this problem. Been reading tons of info on this issue for different posts on here. I just went and got some Black RTV aand sealed around all 4 outer lights. I will be testing the results tomorrow afternoon. Hopefully with decent results. I inspected all the center ones and they all seemed to be holding up well. I also read about a few with weatherstripping issues. Also inspected and didn't find anything obvious. Crossing my fingers and hoping for the best....Thanks

Let us know the results. Always good to get feedback on what works and how you did it. Good Luck!

Well, it still continued to leak after sealing the marker lights. The Hummer dealership I use has closed it service center and I am now forced to use a regular GM dealer. My best guess is weatherstripping that even though it looks good, may not be doing the job. My only other guesses, from reading past posts, is the windshield or body seam. Dropped it off tonight and hope to know something within the next couple of days.

Did you make sure to seal around the wire hole grommets UNDER the marker lights? This is usually where the water gets in and runs down the door columns and reaches the carpet. Just sealing around the marker light gaskets usually doesn't fix the problem. At least it didn't fix it for me.

I did, removed the grommet, cleaned and sealed with a bead around the hole and then after re-inserting the grommet.

Hello , you might also check the windshield itself especially if its been changed before and also ac evaporator drain is not clogged mostly for passenger side.
