Where is the CD changer in your 1999 ford windstar?

A 1999 Ford Windstar's CD changer wasn't built into the car itself like some later models. It was a separate, optional accessory that would be installed in the trunk, usually in a dedicated space or possibly under the cargo floor. There wasn't a standard location. You'd have to check your specific Windstar's trunk to see if one was installed and where it's located.
