‘22 389 day cab. Driver’s side door seems to be shut tight but once I get going about 45mph and it starts whistling, like birds chirping. At first I thought it was the window as if I cracked the window I couldn’t hear it. But I think it was simply masking the noise as I now hear it occasionally with the window open.
It doesn’t act loose or vibrate when closed.
When outside i see the bottom corner by the handle often times doesn’t close flush.
Both our shop and peterbilt are uninterested in addressing the issue…
So is there any adjustments to the drivers side door??
