ticky, rattly windows

my 07 tacoma DC has developed an annoying sound: a small rattling/ticking noise in the passenger window. It's only happens over roughish round, and it only happens when the window is rolled up. So about 1/2 rolled down it goes away. Like the rubber seals aren't holding it tight enough and it's rattling around just the tiniest bit?

I pushed, pulled, and prodded at the seals to make sure it is all tight, but no avail.

thoughts?

 

Mines does the same thing on both front windows and the rear sliding glass is hard to open now.

I think its because of offroading.

I'm going to take it back in as I'm in warranty. I'm just lazy...
