Got a cracked or shattered driver's side window on your 2004-2010 Toyota Sienna? This replacement glass is exactly what you need. It's the left front door glass, made from tempered safety glass (so it shatters into small pieces, not sharp shards). Direct fit for models from 2004 through 2010 – just match your year and trim. The part number is FD21974GTY, and it's from NAGD, a reliable afterglass brand. Comes brand new in protective packaging, ready for installation. If you're a DIYer, you can tackle this with some basic tools and a helper, but since it involves removing the door panel and regulator, maybe watch a tutorial first. For pros, it's a straightforward swap. Fits all Sienna minivan trims – CE, LE, XLE, etc. Includes a manufacturer warranty for peace of mind. Always handle with care – tempered glass is strong but can chip on the edges. Perfect for fixing after a break-in, weather damage, or just old wear. Get your van sealed up and quiet again.
