Windshield Install question

[silotwo]

Does anyone have the specifics on installing a windshield in an 04 996C2? I had a new windshield installed from the dealer, they subbed the work to safelite, and now when the sun is NOT out it sounds like hail hitting the windshield. I had the luggage lid open while driving back in april, dealer replaced the hood and windshield and during the painting process they removed the roof rails. I never had this noise prior to the repair.

My contention is that when the sun is out it is generating heat through the windshield and thus making the seals more pliable. When the sun is out the noise is completely eliminated and it is a pleasure to drive the car. When the sun goes down the car makes so much noise it is nearly intolerable to drive the car. The dealer is now playing with the roof rails but it has made no difference.

I am wondering if the install on a Porsche is perhaps different than on other makes of vehichles. I read the TSB on the rope solution but it is not clear to me that this apply's to a 2004 model.

I really need help here, I have had the car back to the dealer five times already and I just want to be able to use my 996. Any input or suggestion will be greatly appreciated. At this point I am even willing to pay out of pocket if I can find a glass shop that is well versed in this car. I live in Allentown, Pa.

Thanks in advance.

Thank you. Interestingly enough I read through the thread you recommended and considered that the seal could be the problem and that even though it is brand new a good cleaning and lube might be worth a try. I just picked the car up from the dealer because they called and said "we made some adjustments". Because the problem only exists when the sun is not out, I agreed to test drive it tonight. Anyway, when I got there I checked it out and I could see an oily look on the roof at the windshield seal so I pulled it back and sure enough the sprayed the heck out of it with some penetrating oil. I could help but wonder if the dealer reads renntech. :) Then I noticed they somehow cheated the plastic cowl pieces and have the ends raised up almost all the way off the lower seal at the windshield. The entire plastic cowl is quite loose now and when I press on it I hear what I think is the sound I compare to hail hitting glass. So far the noise on the interior is gone but now I have a vibration and rattle which I believe is from the entire plastic cowl assembly being so loose. Get this, I opened the hood and the plastic shield that connects with the plastic cowl is barely hanging on. They have the screws so far backed out it is almost laughable.

I am going to drop it back off and ask that they properly install the plastic cowling and clean and lubricate that lower seal.

The good news is that I am pretty confident that they found the source of the noise, I am just not comfortable with the solution.

I should have posted here a month ago, I'd probably be happily motoring down the road by now. :renntech:

Thanks for your help.
