There is a TSB on windshields that sounds like the exact scenario you all are describing. I'd take them to task if it were me. XONXOFF...your windshield crack is right where this TSB refers to. You need to refer to this when you go to the dealer.
Body - Windshield Replacement Precautions
Bulletin No.: 03-08-48-004
Date: August 01, 2003
INFORMATION
Subject:
Guidelines to Prevent Cracks in Replacement Windshields
Models:
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. <span class="ev_code_RED">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.</span>
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.
