I have the latest factory "fix" and adjustment for the windows on the 456 GT. Despite this, there is still a 3 mm gap in the bottom rear corner on each side. When I got caught in a heavy sudden rain, we had two small rivers flowing into the car. Any suggestions on how to plug the gap or adjust the liner to seal properly ? Thanks Boxer42
This post isn't going to get you closer to an answer, but our '97 456 has the same challenge yours does. We haven't been able to learn much about the "factory fix" so if you don't mind, can you explain what you've had done to your doors/windows/regulators, so far?
The "factory fix" which was done on my car was actually done by the dealer. My understanding was that this was bascially adjusting the window, regulator, and seals. Currently my windows seal well with the exception of the gaps in the lower back corner. This is due to a design problem with the rubber liner. Other than sticking small rubber pieces in the gap when it rains, I have not come up with any decent solutions.
