* Online used parts marketplaces: Sites like eBay, Amazon, and Craigslist often have used car parts for sale. Search specifically for "Ford Taurus CD changer" along with your Taurus's year and model. Be sure to check seller ratings and ask questions about the condition before purchasing.
* Junkyards (auto recyclers): Local junkyards or salvage yards that specialize in Ford vehicles are your best chance of finding a used CD changer. Call ahead to see if they have any Taurus models in stock that might have a working CD changer.
* Ford dealerships (long shot): While unlikely to have new CD changers in stock, it's worth a call to your local Ford dealership to inquire. They might have a used part available or be able to direct you to a reputable source.
Keep in mind that even if you find a used CD changer, there's no guarantee it will be fully functional. You might need to factor in the cost of potential repairs or replacement if it's faulty. Consider if the cost and effort are worth it compared to using a modern audio solution like a Bluetooth adapter, USB drive, or streaming service.
