After 14yrs of trouble free operation, our sunroof is letting in some wind noise at highway speed when closed. It appears to be still water tight however. I have tried poking around the perimeter, pushing up, pushing down, whatever to find the culprit, but the best I can say is the wind is heard through the front passenger side of the sunroof. Are their any adjustment screws for tightening up the roof for a better seal? TIA
