Help - Whistly Window seals

[Michel]

Hi All,

my Grand Picasso has a Whistly Window - rear passenger, when above about 55mph. It's quite annoying... what is the best way to resolve this? is there something I can clean and lubricate the seals and channels with? I was thinking a light smear of silicon grease...

Thanks for any ideas,
Mike

I do have some silicon spray that you could try.
