Our libby gets a crackling noise in the windshield when the temp drops down...drives me nuts, wife turns the radio up louder. Sounds like putting plastic beds in a glass jar...got to be a bolt lose or something up there or the windshield is rubbing on something, the cold shrinks everything just enough to get the noise. Yuo maybe having same problem as the rubber components of suspension shrink with cold allowing things to rub. The older it gets the more wear they have thus getting louder when it does squeak.
I know how you feel, little noises like that drives me nuts.
