Default GXP Window Noise

How can I fix this? I sprayed silicon lubricant between the glass and the outside weather stripping, it didn't help at all. This is super annoying.

i always use dielectric silicone grease on all the rubber parts. Its also what most service manual's recommend. always used it on the seals around my windows , and the doors , and all still looks brand new , and i don't have that sound It may leave a bit of a mess for a little bit as it gets absorbed but eh it'll wash off.

Thanks for the reply. I ended up fixing this and the cause was a lack of lubrication on one of the tracks.


I had to take the door panel off and remove the noise insulation.





It is very important to lubricate both the left and right side of the track (front and back too).



I used my gloved fingers to apply white lithium grease. It is quiet once again. I hope this helps anyone else who has to deal with that obnoxious sound.

I had no idea what the issue was, haha. I did take your advice and it definitely helped the window go up a lot quicker and smoother, so I did it to all of the windows. Thank you.
