Thread: Hummer H2... Water Leak... UGH!!!

Getting so frustrated with this, I just can't seem to find the source and get it fixed. Will likely be turning it over to the "Stealership" soon if I can't. But will give it one more DIY try this week or weekend. Luckily it's drying up in the NW this week.

If there are any other H2 owners on here that have been through this, and you have any tips or advice, I'd greatly appreciate it!

Thanks!!!

What and where is it leaking? A little more info and we might be able to help you out!

Sorry... good point.

It looks to be coming from the A pillars, as well as the back passenger pillar - a "new" one I just found today. Common source that I've found are the roof lights. I've gone through and re-sealed them. But will redo them again, just to be sure. Especially since I've found the new leak today.

Essentially the water tracks along the bottom of the sides/sills of the body, not in the doors. And since I park at an angle on my driveway, they're going to the low point, which are the "wells" on both rear passenger sides.

Does your truck have a sun roof? You should check the seals there and see if the channels that run are cleaned buddy had an issue with the drain holes being plugged and water would just pool.

Nope, no sun roof. But thanks.

It's the roof lights! Use body shop "dumdum" to seal them up

I already sealed them with some rtv, but I don't think I did a good enough job. Thanks for the tip on the dum dum. Just looked it up, and found info on a readily available type that Home Depot sells. Evidently it's electricians putty for sealing conduits, so maybe that will work better? Unless you have a tip on another type of dum dum that I could pick up at a local hardware shop?

Thanks for the help!

Have you tried any H2 specific message boards?

I have the sut and mine leaks a little in the back by the roll down window!

I had a leak where the groment of the drivers door leaked for the wires going to the door. I resealed the stupid top lights 3 times and the problem persisted. The water runs down the a-pillar and then came in by the kick panel and would make the whole left side of the car wet..........

Good luck
