Used Mercedes-Benz exterior quarter window slot seal / trim, OEM part number 1666902180, for the left rear position. This genuine used part was removed from a donor vehicle. It serves as the weather seal and trim piece along the lower edge of the quarter window, preventing water and debris from entering the body panel gap. A cracked or missing seal can cause interior moisture or wind noise. This is a direct OEM replacement for the listed Mercedes-Benz GL and GLS models.
