[Vwdiesel] 91 whistling windshield

[Val Christian]

When new, my 91 whistled.  Not all the time.  The wind had to be 
right, the window's had to be closed.  A rag stuffed right above 
the speedometer area cut it down.  The dealer seemed unable to 
find or repair the problem.

One day a dump truck dropped a 2" rock which bounced for 10 or 15 seconds
before finally hitting the windshield.  The replacement didn't whistle.
I assume the factory window had some small gap in the sealant.
