Absolutely no scratching on window what so ever, when window is dry it works just like new and all the other windows. But as soon as it rains or went through a car wash it has a low hum or growl when rolling up and down until the window it dry again then it works fine again.

I have the exact same issue whenever it rains or go through a car wash, the driver side window will make loud growl when the glass gets near the down position and it makes the noise going both up and down. The dealer has replaced the window actuator and the internal seal, but the noise is still there when ever it rains or I go through the car wash. Dealer is asking GM what to do. My truck is a GMC Sierra X31 2022.
