Windshield Crackling Noise

If you look at the base of the windscreen whilst outside the car you'll notice a plastic strip running across its base. This plastic strip catches dust and grit underneath, and over time (if not cleaned), the grit will manifest itself as a creaking sounds in the cabin. Try pressing along that plastic strip you'll most likely hear the sounds you've been hearing inside the car.

If you run a high pressure hose along the base of the windscreen, focusing on getting the water under the plastic strip, you will clear any grit/dust from between the strip and windscreen. The end result is no more creaks. Enjoy
