SUNROOF PROBLEMS

[K9sH3]

I was also told that because I added a aftermarket air deflector, that this was causing the clogs?? Don't know how that would be it, but I took it off and now I am hoping it rains. To see if I still get the water leaks.

I had the same problem w/ the air deflector and finally removed it. It seems that with the deflector, water that would normally pass down the front of the roof line gets trapped inside the deflector and overloads the drain tubes in the sunroof.

I also had problems with the tubes getting clogged with the deflector, as small debris gets caught by the deflector. I actually knocked the tube off the drain connection trying to clear a clog and had a MAJOR flood in the passenger area.

After the 3rd warranty service trip for the leak(s) the dealer replaced the carpeting.

The dealer also replaced the windshield once and re-sealed the roof marker lights 3X before the leaks were solved. (I hope - so far so good)

Lose the deflector and hopefully the problem will clear up.

Good luck.

You just exactly describe my problems... I take it that all has cleared up for you and How did you go about getting the dealer to replace the carpet??
If you ever get to FL, I am buying whatever you drink for you.

When we brought it back for the 3rd time for them to fix, it poured overnight while the truck was outside and they saw for themselves how bad it was. My wife then drove the service manager crazy with phone calls (she's good at that) and told them we weren't taking the truck back unless it was changed.

I liked the look of the deflector, but realized that it was a major cause of the leaking problem.

I had one more leaking episode after that, much less water, that they said was coming in from the marker lights. They re-sealed them (again) and so far it has held up. We had some heavy rain in NY last weekend and the truck was dry.

What part of FL are you in?

I live in central FL, Beachside.
I am going for the carpet 2moro.. I am very lucky I take my H3 to a GMC dealer in Cocoa FL and I have never been treated so well. So I am hopefull they will get it done for me.
Thanks again.

Well it rain very hard and for a long time last night, got up this morning around 11am went to the H3 and the passenger side floor was soaked, Drove it to the dealer to show them and ask about new carpeting also. They agreed to keep it and replace all the padding and to replace the right side panel of the dash. They saw that is was discolored from the rain coming in.
I told tham about resealing the roof marker lights and that to will be on there agenda. I ask to have all the sunroof seals replaced.
Again, Thanks for the help.

Great news for you finally! It's great when another member had the same problem with a fix .. and then we can learn about the fix for our H3.
