water leak

[lonePalm]

Im glad you had this problem, No offense I'm having the same issue and it has just happened on an off for the past month and it is coming out of the home link area. That small hole there acts like a little drain, Damn thing! Now I know what to do to fix it.

Remember- anytime you have your windshield replaced, tell the glass company NOT to use the lower factory glass positioners or else you'll end up with a long horizontal crack weeks or months down the road.

There is a TSB for this but I don't recall the number off hand, print a copy and give it to them to save a lot of hassle later.

Are you referring to a crack in the windshield itself, or in the sealing? Thanks for the info...Jamie

Well, I have RTV'ed the cab lights but I am going to remove all three amber center cablights. I have found flat button plugs for all three lights. I will be removing and sealing them. I will post a pic when I am done.
Two sizes are needed to plug. 3/8" (6) and 1-1/4" (3) and clear RTV.

The windshield itself will develop a horizontal crack that begins at the stress riser created by the factory glass positioners. Here's the old post from Klaus 2/7/2004:

Info - Guidelines to Prevent Cracks in Replacement Windshields #03-08-48-004 - (08/01/2003)
Guidelines to Prevent Cracks in Replacement Windshields
2003 HUMMER H2

This bulletin is being issued to advise dealers regarding correct replacement of the windshield.

After removing the windshield, there will be two plastic blocks visible along the lower edge of the windshield opening, each located near the windshield wiper arm transmission spline. These blocks are assembly aids used only when installing the windshield at the plant. They must stay in place so as not to open a hole where they mount. However, upon installation of a replacement windshield, care must be taken to assure that the glass does not come in contact with the blocks.

After applying the urethane and positioning the windshield, leaving an air gap (3) of 1 mm (0.040 in) between the block (4) and the windshield (2) , compress the urethane only as much as necessary. This will assure that the glass does not come into contact with the blocks. If contact is made with the block, body flexing may cause the replacement windshield to crack. Cracks along the bottom of the glass are an indication that the glass is contacting the blocks.

Tape (1) the windshield in place. Do not remove the tape until the adhesive cures.

Important
When subletting a windshield replacement, provide a copy of this bulletin to the persons involved in the replacement.

See my post "Another Water Leak Thread". Your leak may be coming from the roof seam like mine was.
