This window, pretty simply, lets you see out and lets light into the vehicle. It also rolls up and down, of course, and seals against the weather to keep rain, snow, and wind out of the car. It's a fully assembled unit, meaning the glass is already bonded to the frame, the regulators are attached – everything you need, basically, to replace the existing window. Think of it as one piece of the overall structure that provides visibility and protects the inside of the car. It’s part of the body, but it’s also important for safety. It contributes to the structural integrity of the door and, naturally, allows passengers in the back to see what's going on. Well, a damaged rear window obviously affects your visibility, which isn’t ideal. But beyond that, a window that doesn't seal properly can let water inside, leading to rust and damage to the interior. Also, a broken window compromises the security of your car. You’ll notice if this window is cracked or won't roll up and down smoothly. If you’re looking to get this replaced, a site like Fixparts Online has these in stock and can get one to you pretty quickly. They're generally a straightforward swap, but you’ll need some basic tools and potentially a bit of patience.
