One Original 1996 Buick Park Avenue & Park Ave Instrument Panel Switch (Instrument Panel/Interior Lights, Twilight Sentinel and Traction Control) Part #25620417. (Master Switch located to the kleft of the instrument cluster) This switch was acquired for use in my personal vehicle but car was sold before part was installed or tested. I have NO IDEA whether it is functional or not, but I have no reason to believe it is not operational, just be clear, you are purchasing with NO WARRANTY, RETURN or REFUND. I also have NO IDEA what other years or models it may fit. Lucky winner adds $0 USPS shipping in USA Only Please. International orders, please email for shipping costs.
