I've been lingering on this site for a while...but never have posted before.
Anyways, I've had my 2003 H2 for about 6 months now and I love it. But a few issues have come up. First off, after a bit of driving my RPM's will start to jump around a bit, but just for a second or 2. (changed fuel filter & had the cats replaced because they were clogged)
Also last night it rained really hard, and it was leaking water from the box that has the dome lights and the garage door buttons.

Any ideas what these problems could be????

search on leaks...there has been much talk on that.

any idea on why my RPM's are jumping around??

no, TVAn you must be lying. These vehicles are impecable. Nothing like you have described could have ever happened to a Hummer.

Mine leaked in the same area. The seal on one of the roof lights had a split in it. New light assembly and siliconed them all. Hasn't leaked since.

FYI, watch out for your radio. The water dripped and ran right into the DVD slot on mine and messed up the touch screen for a while. It was fine after it dried.

alright...thanks a lot...I'm definately gonna get it fixed as soon as I can so I dont jack something up

alright, maybe I'm a dumbass, but I have been searching, where can I find a new seal to replace it with, or new light assembly

Use RVT sealer...you can pick it up at the auto parts place. Do not get the clear stuff...

yeah, the clear does not last nearly as long. I am not kidding...

I've had the same problem. It seems the dealer identified that leak to my PIAA light bar on the roof and fixed that particular one and then it started to leak out the passenger side sun visor. Still leaks after 4 attempts at the dealers. They have been terrific though in trying to accommodate me. My leak isn't consistent though. It hasn't leaked in rain storms or in my driveway which has a slight pitch to it. It only seems to leak if it rains and I am parked in an open area..The dealer has said it is a problem and they are trying to figure out where the darn thing is coming from..Good luck
