Windshield area makes snapping noise
2002 SLE W/134K. When I go over an uneven road surface I hear a crisp "snapping" sound coming from the windshield area above the passenger side dash. Not potholes, or bad road slabs - just rolling uneven pavement. It only happens when it is cold, like under 20* - so all winter here in Iowa it has been doing it. I never hear it in the summer. I have checked for lose struts and other stuff under the hood and car, and under the dash. It is the factory windshield with no cracks or chips. Any ideas ? Something other than the windshield ? Cracked weld somewhere ? Why only when cold ?
