express sunroof = express water flow

[timgco]

Damn it! First problem poped up.. or I should say in. Parked in the driveway. It's on a hill that faces downward away from the house. when running the hose over the roof (not dirrectly on the sunroof either) the wind deflector fills up with water. than it comes into the truck onto the dash. http://www.elcova.com/infopop/emoticons/icon_mad.gif M.F'r http://www.elcova.com/infopop/emoticons/icon_mad.gif

I check to see if it was the marker lights; it wasn't.

I checked to see if it was the antenna on the roof; it wasn't. The water comes in through the sun roof somewhere in the front.

I'm sure this insn't the first sunroof to have water coming in either.

So here's my Questions.

1) is this a simple fix? replace sunroof gasket?

2) how does the sunroof come out? from the inside or pull up from the outside?

Yes, the dealer will be doing this, as it only has 2200 miles, but the rack is going on Monday. If the sunroof has to be pulled from the outside, i can just see some dumbass screwing up all the wiring on the lights.

Any thoughts?

Oh, drains seem to be Ok too. dumped a few LARGE glasses of water down them and they drain fine.

[PARAGON]

The whole sunroof assembly does remove from the inside but the it looks like the whole headliner would have to be removed also.

[tower]

Forgive this really dumb question, but it's something I might overlook. Are you certain that the suroof was closed all the way? Did you open, reclose and retest?

Bulletin No.: 03-08-57-002

Date: May 07, 2003

TECHNICAL
Subject:
Water Leak From Sunroof Area (Replace Drain Hoses)

Models:
2003 HUMMER H2

Condition

Some customers may comment on a water leak from the sunroof area.

Cause

One or both of the drain hoses from the front corners of the sunroof module may be kinked under the instrument panel (IP).

Correction

Replace both sunroof front drain hoses with an updated design part using the following procedure:

[LasVegas]

I would clean the seal thoroughly first. You might want to treat it with a conditioner, silicone, etc. Then operate it open/close & see if it appears to be seating & sealing correctly. If it still leaks, I would suspect the drains. The drains may be able to handle a "glass" of water but not the "pond" you created.

[LasVegas]

There are also mechanical adjustments to the sunroof. Here's the procedure. If you suspect this is the problem you may want the dealer to do this under warranty.

1. In order to adjust the glass height, the sunroof glass must be in the zero, closed, position. IMPORTANT: Do not remove the screws from the sunroof mechanism.
2. Loosen the 4 adjustment screws NOTE: Refer to Fastener Notice in Service Precautions.
3. Adjust the rear glass panel (1) so that it is flush with the roof panel (3), 0-2.0 mm (0.079 in) above 3. Tighten Tighten all 4 adjustment screws to 7 N.m (62 lb in) .
4. Adjust the front glass panel (2) so that it is flush with the roof panel (3), 0-2.0 mm (0.079 in) below 3. Tighten Tighten all 4 adjustment screws to 7 N.m (62 lb in) .

LasVegas pretty much has nailed it. More than likely your drain hoses are kinked. We have been seeing alot of them lately, and all I gotta say.. The repair SUCKS...

Even though the hoses are kinked, they will still flow, but not very well. Use "glass's" of water is not enough fluid to cause a backup....

[timgco]

Well, the dealer will have to check them I guess. I like to do the work myself; this way I know some hack doens't screw something else up. http://www.elcova.com/infopop/emoticons/icon_rolleyes.gif

I'll let you all know what they say. Thanks for the info.

Good call, as I am sure you "really" don't wanna remove your dash http://www.elcova.com/infopop/emoticons/icon_biggrin.gif

I have yet to see an 05 with kinked sunroof drain hoses. It was a large problem on 03 models built before or around Feb of 03. Then they made some changes and it doesn't seem to heppen. Now sometimes I see them clogged with twigs if people like to park with the sunroof open under trees a lot. Due to your low mileage I doubt that. I do wonder if maybe your sunroof was cracked open and you didn't notice. Sorry, but from what I see everyday, that is my best guess. Either that or your sunroof drain tubes are getting clogged, or your sunroof is seriously out of adjustment, which you should be able to obviously see.
Goodluck, let us know how it turned out.

We have seen 2 of them so far that I know of....

[timgco]

You guys mean that I have to close the sunroof all the way so water will not to leak in? http://www.elcova.com/infopop/emoticons/icon_rolleyes.gif

Yes, I checked! When the sunroof is all the way closed, and the water is pooled on top of the sunroof damned up by the wind deflector, it leaks in. Next Tuesday it goes into the dealer. He said there should be no leaking if it is closed all the way. said it may need ot be adjusted (may not be clsoing 100%, maybe only 99%) and this is causing the issue.
I'll find out next week.

[Hummertech]

Crash, have you seen 2 so far on the 05's? If so, have they been kinked where they come out by the wiper motors like on the early 03's?

[crash]

To the best of my knowledge they were pinched in the same place. I have been lucky and haven't personally had to do one yet (The lower guys usually get stuck with them). And I would probably guess they were very early in 05' production, if I were to guess.

[Hummertech]

You talk like fixing those is a crappy job.
I take it that you guys don't go from the wiper motor end to try to unkink these. That's how we do it and it's gravy.

[timgco]

Ok, so went the dealer today and found out a few things.

Check engine light was on- replaced bad gas cap.
Headliner was loose- reaplced retainer.
Sunroff leaks- There was a wiretie (sp.?) stuck into one of the drain holes. they told me that ll of the H2 sunrrofs leak when water is puddled on top and that's why their are drain holes. My drain holes weren't allowing for the water to drain fast enough.
not sure I like what I was told, but we'll see what happens. I have to have a tone of water up there for it to leak or balst it with a hose dirrectly for it too leak now and it's only a few drops. So under normal situations, i think I should be fine. Any takes/ comments/ concerns?

[LasVegas]

My comment is that it shouldn't leak at all...period. I would not accept that Tim.

[Hummertech]

If the drain tubes are not restricted, you can puddle as much water as you want on top of that sunroof and it should not leak.

[tower]

With a small leak, should you travel to the snow, overnight freezing will solidify and expand whatever water is in the leak. Since water has the unique property of occupying more volume as a solid than a liquid (that's why ice floats), the leak will be forced to expand each time this happens. That’s why were all saying, despite the hassle of going back with this complaint again, get them to fix it right. You'll be happy you did when your warranty expires.
