squeek right above driver's visor?
 

In my '02 ML500 I have an intermittant squeek coming from right in front the middle of the driver's visor toward the top of the windshield. I checked outside nothing is there. It doesn't seem to be the sunroof, wipers or ceiling liner. ANY IDEAS or anyone else hear it on theirs? It sound like to pieces of plastic rubbing almost making a morse-code type chatter.

I have a 2001 ML320 with a similar noise which appears to come from the right side of the dash at the window and accross the dash. The dealer has worked on it about 8 times in the past 6 months and been unsuccessful. Very frustrating.
