My w126 300SE recently had a similar problem.
Do a search on the archives.

My indow regulator had to be replaced. Some of the teeth were shot. The sheetmetal frame onto which the regualtor is bolted bends a bit outward when the window is closed too tight.
This can cause a tearin that area. That can be expensive.
Open up the door panel and inspect .
For the time being, just roll up the affected windows slightly snug then tap it in until no wind noise is heard.
No need to jam it all the way up, sp. with an automatic
system.

Simple cause may be dirty-sticky window guides.

Don't let it go!!
good luck
