This used BMW upper dash defrost vent (OEM 9257973) is the left-side outlet that directs air onto the windshield for clearing fog or ice. It also replaces 9279287. Designed for the X5 with the 2.0L PHEV, 3.0L gas/diesel, or 4.4L V8 engines. A cracked or broken vent can cause weak or misdirected defrost airflow—a common issue that leaves the windshield slow to clear.
