Whistling from Driver-Side Front Door

[sidepipe]

Hello all! I replaced my driver-side front window recently and replaced the window frame guide. After getting everything back together and driving the car I heard a faint whistling at the top of the window which wasn’t present prior to the replacement. Upon inspection I noticed around a 2mm gap at the top right corner of the window frame guide where the window frame guide should sit against the aluminum trim. I tried loosening the 3 compensating socket bolts on the sides of the door and my adjustment helped a little, but I am still left with a gap. My next plan is to heat-up the area with a heat gun and gently pull the area where the gap is… would this be a bad idea? Anyone have any noninvasive suggestions for addressing this?

Could be the fram or the window is warped. Does the frame seal properly around the door?

The frame does seal properly, but I think the outside (see picture from original post) of the frame is misshapen. Do you think heating the area with a heat gun and gently pulling the area would help bridge the gap?
