Here's where you should look:
* Online Auto Parts Retailers: Sites like RockAuto, AutoZone, Advance Auto Parts, and Napa Auto Parts are your best bet. Use the year, make, and model of your car to search. Be very specific in your search terms, using "manual" and "hand crank" to avoid getting power window parts. Check multiple sites as their inventory varies. You might need to specify the body style (sedan, coupe, etc.) as well.
* Junkyards/Salvage Yards: This is a good option for finding used parts. Call local junkyards and salvage yards and ask if they have a suitable Alero or Grand Am in stock. They are more likely to have the parts you need.
* eBay: eBay can be a hit-or-miss, but you can find used parts there. Carefully check the seller's description and photos to ensure it's the correct part for your specific year and model.
* Local Auto Parts Stores: While less likely to have this specific part in stock, it's worth checking your local auto parts stores. They might be able to order it for you from their supplier.
Important Considerations:
* Part Number: If you can find a part number from a parts catalog or a previous repair, that will make your search much easier.
* Interchangeability: Parts from similar GM vehicles from that era *might* be interchangeable, but it's crucial to verify compatibility before purchasing. Don't assume.
* Used vs. New: Used parts are more affordable but may have some wear and tear. New parts (if available) will be more expensive but should last longer.
Remember to carefully check the part when you receive it to make sure it's in good working condition before installation.
