You may only think about the rubber seals around the windows and doors of your vehicle, but there are actually a number of locations where you can find weatherstripping.
Vehicle weatherstripping falls into five main categories, including door, window, windshield, trunk and other. Now that you have a general idea of the various types of weatherstripping, here is a high-level overview of the type of weatherstripping that you can find on your vehicle.

1. Door

Automotive door seals attach to the outside border of your door and seal the door to the body of the vehicle. This weatherstripping keeps out wind, debris and water and also helps keep the door closed. Some door weatherstripping is held on with clips that snap into holes on the door. Other door weatherstrippipng is meant to be glued in place using an automotive weatherstripping adhesive.
If there is a frame around the window, the rubber seal will have an “O” shape that surrounds the perimeter of the door as well as the window frame. But if there is no frame surrounding the window, then the seal has a “U” shape and attaches vertically to the rear and front of the door, then connects across the bottom.
Some door seals mount to the body of a vehicle and others install onto the door. In most trucks, the weatherstripping attaches to both the body and the door. There are three types of door weather seals: glue, press-on and clip-on. They are vital for keeping out moisture along with wind and debris.

2. Window

Window weatherstripping is located around the edge of the window glass and helps the window move up and down without sticking. It also keeps the interior of your vehicle safeguarded from water. There are three primary types available, depending on the kind of vehicle you drive:

• Beltline: Also known as the “window sweep seals” or “window fuzzies.” You might even know it as “the fuzzy stuff at the bottom of your window.” Beltline are applied to each side of the door glass at the bottom. Made of rubber with felt-like material on the inside edge, they allow the glass window to roll up and down while keeping debris from falling into the door panel. Some mount onto the panels and others install onto the door shell.
• Vent window seals: Vent windows are the small, triangular or rectangular-shaped windows located in the front door just in front of the primary driver or passenger window. These are typically found in classic and antique vehicles as they have been phased out in most newer vehicles. The vent window requires two seals – the vent window seal and the vent post seal. The vent window seal mounts to that portion of the window frame on the door shell and the vent post seal mounts to the vertical division bar located between the primary window and the vent window.
• Window channel: Also known as “window run channel.” You apply them to the inside of a door window frame to act as a guide and seal for the perimeter of the glass. The seal also prevents the elements from reaching the interior, reduces rattling, and is made of soft rubber to avoid scratching the glass.
• U-Jamb seals: Also known as “quarter window lock pillar seals,” are located at the front of the quarter window near the bottom corner. It’s also the frontmost and upper edge of the quarter panel, and the solid or hollow piece of rubber is often U-shaped. A U-jamb stays connected by screws, adhesives or clips to prevent debris and the elements from entering your automobile.

Some SUVs also have quarter window vertical seals. These tend to be overlooked when it comes to weatherstripping. They attach to the front edge of a quarter window. Quarter windows are located between the front side window and the back portion of an suv.

3. Windshield

Windshield weatherstripping surrounds the entire windshield perimeter for water and wind prevention and to ensure the glass stays connected to the vehicle. Some cars have windshield weatherstripping laid on top of a windshield that’s glued to the car, while others have it installed at the same time as the windshield. The rubber component stays in place thanks to pressure from the glass, or adhesives or clips.

Within the windshield category, there are two distinct types:

• Header seals: These span the top windshield frame and are on vehicles with convertible or Targa tops. The rubber piece seals the convertible’s top structure by running along the A-pillars, meaning they seal the windshield and door. Headers stay in place with glue, clips or screws.
• A-pillar seals: Also known as “windshield pillar seals,” these attach to the A-pillar, located at the side of the windshield. Its purpose is to seal the window frame or door glass to the windshield.

4. Trunk

Automotive weatherstripping replacements also include trunk seals that connect the trunk or deck lid to the body of the vehicle. Not only do they keep rain, snow, and wind from running into your back end, but the seals also help channel water toward the ground in stead of letting it stay on top of your trunk and rotting it out. The seal keeps your trunk lid secured to the body of the car.

5. Other

Roof rail weatherstrips attach to the roof of a car where the window frame connects. The rubber part helps keep rain, wind, snow and dirt from trickling through to the interior of your vehicle. If your roof rails get damaged or are not installed correctly, you will often hear a great deal of wind noise while traveling.
