Why does my window squeek :(

Both of my windows were doing the same thing, it is pretty annoying. Mine was coming from the rubber near front of the window (by the speaker on the 460 system). I was able to get a very thin coat of grease between the rubber and the window and it stopped it for a while, then reapplied when needed.
 
LMAO...mine does the exact same thing and I thought it was something the previous owner did after taking the door panel off or something.

What sort of grease did you use?
 
trick

RainX works wonders for this problem and keeps the rain from blurring your vision too. Just remember any harsh soap (like a touchless carwash) will take it right off and you will have to reapply.

Works like a charm though. :nice:
 
Yep, just get some kind of grease and spray in the little triangle panel part of the door. Should go away. I think ford sell a certain kind just for that.
 
I used simple (and safe) WD-40 on a piece of sponge to lube that area around the Mach speakers.
BTW, I've found taking a typical small kitchen sponge and cutting it (while dry) into various sizes and shapes makes some of the best applicators for stuff like this (as well as Black Magic on the windshield cowl, etc)
 
On my '02 GT the squeaked like crazy. But on the '03 Mach it's not so bad, it looks like ford put in some sort of thin gasket between the rubber and glass now. But it hasn't completely remedied the problem. They still squeek in the cool or damp weather when I'm rollin them up. Summertime it's quiet though. I dunno if you can retro fit the part I'm talkin about or wether or not it's even available. Anybody else know what I'm talkin about?
