Purchased in a lot with assorted automotive parts, most were new and unboxed.

Here is what I found on this item::

The car window switch with the number FC01-66350A is primarily associated with Mazda vehicles.

Specifically, it is a power window switch for the 1989-1991 Mazda RX-7, particularly the driver's side (left-hand) switch. It's listed as being replaced by or superseded by the part number FC01-66-350B, meaning FC01-66350A is an older version of that part.

You may also find some aftermarket listings or cross-references indicating compatibility with certain Mazda 6 models (specifically 2002-2008), but the most direct and consistent OEM reference is for the Mazda RX-7.

Sold as is, untested, so please review the part number to determine exact fit. No returns, so make fair offers accordingly
