300E wind noise from driver's door

[hs_300e]

Hi,

I am experiencing wind noise only from the driver's door on my 86 300E (77K)

It is particularly pronounced at higher speeds. If I pull the top rear corner of the door in, the noise reduces considerably. Basic inspection shows that the weather strip on the door is good.

Is the fix as easy as replacing the weather strip on the door, the weather strip that goes around the window or does the door have to be adjusted?

Thank you.
