I have a squeak which sounds like it's coming from the bottom of the back window. I don't have a slider or power slider window, just solid.

I checked everywhere and could not find anything loose...

Anyone ever have this and have a fix?

 

yeah i had the same problem with me it happens whenever i go over some big bumps. I complained about it at first and took the truck to the dealer and they applied a silicon lube in between the window seal and the metal, but about a month after they did it the squeak came back and i havent done anything about it, mostly becuase i normally have the music up so loud i dont hear it. maybe try some silicon lubricant and spray on the outside of the truck around the outer rubber seal, thats how the dealership told me they did it. Good Luck, sorry if this wasn't more help.
