Window squeak

[Nate1616]

Anyone know how to fix a window squeak. I can hear it's coming from the rubber part closest to the dash where that top speaker on the door is. Any solution. I did wd40 and it worked for a day and back to squeaky now:(

Never use WD40 on rubber. It tends to eat most forms of rubber.

Use silicone lube or similar products made for leather or vinyl. Probably even tire shine products since they are made specifically for rubber and so they don't dry out too quickly.
