Weatherstripping basically seals up the gaps around your doors, windows, trunk, and sometimes even the hood. It's made of rubber or plastic, and it comes in a bunch of different shapes and sizes to fit all those openings. Its main jobs are to keep the outside… well, out. That means water, dust, wind, and road noise. It also helps keep the inside in – like keeping your warm air or AC inside, and helping with that snug, sealed feeling when you close the door. Think of it as a barrier between the elements and the inside of your car. It attaches to the body of the car and compresses against the door or window when it’s closed. It's not a structural part, it doesn't hold anything together, but it's essential for comfort and preventing damage. It’s found all over, around the doors, windows, trunk lid, sometimes the sunroof, and even around the hood. You might not even notice it's there when it’s working right, but… It’s important for a lot of reasons. A failing weatherstrip lets water in, which can lead to rust, mold, and electrical problems. It lets wind noise in, which can be really irritating on the highway. It makes your heater and AC work harder because air is escaping. And it can even make the cabin feel colder in the winter, warmer in the summer. You’ll notice if it starts to go bad because you’ll probably feel drafts, hear more road noise, or see water stains. It really acts like a shield against the elements.
