Okay guys, so here's the complete story:
1. Chevrolet replaced my windshield because of the glass delaminating problem.
2. Washed my car and it now had a water leak coming in just above the dead pedal on the left side. Didn't have the problem prior to the windshield replacement.
3. The dealer in order to make good they had Safelite replace the windshield a second time (both windshields we factor GM glass).
4. Still have the same leak in the same place.
If you have had the same problem, what did you do to fix it.
Two times and till there, strange indeed. The only thing that comes to mind at this point is could they has somehow clogged the drain hole on that side, or could there be some slag from the factory around the windshield frame that the installer missed when they put the glass back. Some have had problems with the windshields cracking because of the slag. I know those a pitiful answers Bob, so I hope they find the problem. Good luck sir.
Good thought, but we checked the drain holes and made sure they were clear. Didn't see any slag after the second windshield install.
I'm wondering if there is any type of gasket on the outside A-Piilar? I spoke my dealer, who has me bringing the car in next week. His plan is to have the body shop and Safelite look to see if they can find it.
Okay here's an update on my windshield leak. I brought it back to the dealer and suggested that they leak test the car. I'm posting this so that it may help any other forum member that might have a similar problem.
I told them to put someone in the car with a flashlight, run water of the windshield on the left side and watch for the leak. Then as soon as they see the leak, start to disassemble the interior panels and see where there is water that shouldn't be there is and follow the water trail to see where it comes into the interior.
They discovered that the Outer A-Pillar Trim had a crack along the edge and a screw that holds the trim panel was put in crooked. So the water would run down the inside of the Outer A-Pillar hit the crack and leak into the inside A-Pillar Trim and then run down and leak into the car. Apparently this trim panel was cracked by the guys who installed the first replacement windshield. Which means they put a second replacement windshield for no reason. They should have leak tested the car when it back the first time. Question: Why did I have to come up with the way to find this leak. You would think that the dealer or Safelite would have done this.
I will pickup my car today and the dealer said they did a leak test after the repair and all is dry. Wish me luck.
Experiencing the same issue on the Passenger side of my 17 GS ;the Windshield was replaced twice in the same session - the 1st replacement had de-Lam Bubbles, too.
The 2nd one looked GTG.
The Sub-Contractor Glass Guy used by the dealership, has looked at it twice, we have a 3rd Appt at the Dealership for inspection/leak test tomorrow (12/18/18)
He seemed to put in the screws and weather strip back with no drama, and even used a little Butyl under the screw heads but to no avail.
I surmise that the Pass A Pillar either is cracked like your's, OP, or more likely it is a ferqued up window/A Pillar Weather Strip not quite seated properly.
Some existing, reused parts (especially pliable ones) develop a set and don't go back as neatly or fully as the original installation.

So the best way to decide if a windshield is leaking is to use a blow gun and compressed air. Have someone blow around the edges of the windshield from inside the passenger compartment. You will hear the air come through on the outside, if there is a skip in the urethane.
I discovered that the Windshield Repairman did not reinstall the A Pillar / Window Weather Strip correctly; he neglected to reinsert the weather strip into/onto a Clip at the base of the Right Side A Pillar - this is possibly the source of my leak.
The Left Side is similarly unsecured, In fact evidence of tearing is present.
Are there similar clips all along the A Pillars?

Is this weather strip retainer easily removable without breaking it? How? with a regular nylon molding tool?
It would seem easier to remove the retainer clip from the A Pillar, reinsert it into the hole in the weather strip, then push the retainer clip back into place.
Trying to stretch the weather strip to reattach it while the retainer clip is in situ would seem more difficult and likely to tear the weather strip.

I stopped by the dealer on the way home. The Service writer was a bit adversarial (seems they don't like to correct their warranty mistakes), but a cheerful service tech looked at it, grabbed a trim tool and set to work, The retainer clip is just a 'Christmas Tree' type and pulled out easily. He reinserted the legs back into the WS and subsequently pushed the 'Christmas Tree' back into it's hole - Voilà! The weather strip is re-secured. Upon returning home, I put a hose to the area, let it run for a bit and checked for leaks. The major leak was gone but a minor leak at the top of the window persisted. I looked further and noticed the Weather Strip wasn't fully reinstalled correctly as there was a gap between the rubber and the interior trim piece. I fussed with it a bit, and observed that the Windshield Repairman put the lip of the rubber strip on top of a metal lip that runs the length of the A Pillar instead of under it, which would provide a better seal.
I was encouraged by the success of addressing the main leak, and will set myself to better reseal the Weather Trim Strip if that didn't do the trick (it's late and dark and I'm tired and it's time for dinner!)

Bringing an old thread back from the dead. Did this completely fix your issue or did you still have an issue and need to do something else? My windshield was replaced last year and I've had a leak ever since. I believe it's the weatherstripping causing the leak but even after dicking with the christmas tree plug and making sure the weatherstrip is installed correctly it's still leaking.
Someone once posted that if the C7 windshield is replaced, they need to replace the big weatherstrip that goes across the top of the W/S and down both A pillars even if it looks good.
Our C7 W/S was replaced last Fall (stone crack) and leaked like a sieve. The guy who did the work was clueless, but one of the office guys from Glass America (Gerber) replaced the strip I mentioned, and something separate along the outside of the A-pillars, and now it's perfect.

I posted elsewhere...
The Dealer's Subcontractor botched the job and Dealer (Penske Chebby in Cerritos, CA) refused to correct it,
I took the car to J & D Corvette in nearby Bellflower. A leak test determined that, yes, there was still a leak, which was traced to the passenger A-Pillar Applique being damaged during the WS replacement. A new Applique (or both sides? - I don't recall) was installed and the leak stopped. Out of pocket expense was over $600.

Windshield Leak?
