Broken Glass From the Windshield Or Front Side Window
WARNING: This page is about a different car, the 1998 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.
If the windshield or front side window cracks or breaks (in a collision for example) broken glass may get into the defroster and ventilation ducts. To avoid small particles of glass being blown out of the vents when the car has been repaired, the defroster duct and air vents should be blown through and vacuumed before a new windshield is installed.
WARNING:
Use safety glasses when blowing defroster duct clean or vacuuming.
