When driving faster than 50 mph, there is a bunch of wind noise that stops when I press the driver's triangular window on the side close to the mirror adjustment lever. The seal stripping looks fine. How would I fix this?

 

Shove a quarter between the window latch and the framework...

I managed to fit three pennies.

 

It's likely that the bottom pin is rusted/ broken. Or just worn rubber, these jeeps are only getting older.
