Tools and Materials Needed

Before embarking on the weather stripping replacement journey, it’s essential to gather the necessary tools and materials. Here’s what you’ll need:


  • Flathead screwdriver
  • Trim removal tool
  • Needle-nose pliers
  • Utility knife
  • Clean cloth
  • Adhesive remover (if applicable)


  • New weather stripping (make sure it's the correct type and size for your car model)
  • Cleaner or solvent for prepping the surface

  • Protective gloves (to safeguard your hands during the process)

Having these tools and materials at your disposal will streamline the replacement process and ensure that you are well-prepared to tackle any challenges that may arise along the way. Now that you’re equipped with the essentials, it’s time to roll up your sleeves and get ready to remove the old weather stripping!

Removing the Old Weather Stripping

Before installing new weather stripping, the old weather stripping must be removed thoroughly. Here’s a step-by-step guide to help you through this process:

Step 1: Prepare the Work Area

Begin by parking your car in a well-lit and ventilated area. Ensure that the car’s exterior surfaces, especially around the window where the weather stripping will be replaced, are clean and free from debris. This will provide a conducive environment for the replacement process.

Step 2: Assess the Condition of the Old Weather Stripping

Carefully examine the old weather stripping to identify any areas of damage or wear. This assessment will help you understand the extent of the replacement needed and provide insights into potential underlying issues such as water damage or rust.

Step 3: Use the Flathead Screwdriver and Trim Removal Tool

Gently insert the flathead screwdriver or trim removal tool between the old weather stripping and the car’s frame. Apply steady pressure to pry the weather stripping away from the frame. Take your time and work methodically to avoid damaging the surrounding surfaces.

Step 4: Remove the Weather Stripping Piece by Piece

As you continue to loosen the weather stripping, use the needle-nose pliers to grip and pull it away from the frame. Depending on the type of weather stripping, it may come off in sections or as a continuous piece. Exercise caution to prevent any adhesive residue from sticking to the car’s surface.

Step 5: Clean the Surface

Once the old weather stripping has been completely removed, use a clean cloth and an adhesive remover, if necessary, to wipe away any remaining adhesive or debris. This will ensure a clean and smooth surface for installing the new weather stripping.

By following these steps, you can effectively remove the old weather stripping and prepare the window area for the installation of the new weather stripping. With the old weather stripping out of the way, it’s time to move on to the exciting phase of installing the fresh, protective barrier around your car’s window!

Installing the New Weather Stripping

With the old weather stripping removed and the surface prepped, it’s time to embark on the installation of the new weather stripping. Follow these steps to ensure a successful and secure installation:

Step 1: Inspect the New Weather Stripping

Before proceeding, carefully examine the new weather stripping to confirm that it matches the specifications of your car’s make and model. Verify that the length and dimensions align with the window frame, ensuring a proper fit.

Step 2: Apply Adhesive (if necessary)

If the new weather stripping does not come with pre-applied adhesive, use a suitable automotive adhesive to coat the contact surface of the weather stripping. Be sure to follow the manufacturer’s instructions for the application and drying time of the adhesive.

Step 3: Position and Secure the Weather Stripping

Starting at one end of the window frame, carefully align the new weather stripping with the edge, ensuring that it sits flush and snugly against the surface. Use gentle pressure to press the weather stripping into place, working your way along the frame. If the weather stripping has adhesive, ensure a firm bond with the frame.

Step 4: Trim Excess Weather Stripping

Once the weather stripping is securely in place, use a utility knife to trim any excess material, ensuring a clean and precise finish. Take care not to cut too close to the frame, allowing for a proper seal and preventing any gaps that may compromise the effectiveness of the weather stripping.

Step 5: Test the Seal

After installing the new weather stripping, carefully close the car window to test the seal. Listen for any unusual sounds or air leaks, and visually inspect the perimeter of the window to ensure that the weather stripping forms a tight and uniform seal.

By following these steps, you can successfully install new weather stripping around your car window, providing enhanced protection against external elements and contributing to a more comfortable and secure driving experience. With the new weather stripping in place, it’s essential to conduct a thorough test to validate its effectiveness before concluding the replacement process.

Testing the New Weather Stripping

After installing the new weather stripping, it’s crucial to conduct a comprehensive test to ensure that it effectively seals the window and provides the desired level of protection. Here’s how to perform a thorough test of the new weather stripping:

Step 1: Visual Inspection

Carefully examine the perimeter of the window to visually inspect the newly installed weather stripping. Look for any gaps, wrinkles, or areas where the weather stripping may not be making full contact with the window or the frame. Address any irregularities to ensure a uniform and secure seal.

Step 2: Listen for Air Leaks

With the car window closed, pay attention to any unusual sounds that may indicate air leaks. Run your hand along the edge of the window to feel for drafts or air movement, particularly in areas where the weather stripping meets the frame. Any noticeable airflow may indicate a need for readjustment or additional sealing.

Step 3: Conduct a Water Test

To test the weather stripping’s resistance to water infiltration, use a gentle stream of water from a hose or a spray bottle to wet the exterior of the window. Observe the interior of the car for any signs of water seepage or moisture. If water penetrates the seal, it may indicate a need for further adjustment or reinforcement of the weather stripping.

Step 4: Test During Driving Conditions

Take your car for a short drive, paying attention to any changes in interior noise levels and airflow around the window area. Listen for wind noise or rattling that may indicate inadequate sealing. Additionally, observe how the car’s HVAC system performs, as compromised weather stripping can impact its efficiency.

Step 5: Reassess and Make Adjustments

Based on the results of the visual inspection, air leak test, water test, and driving conditions, make any necessary adjustments to the weather stripping. This may involve repositioning the stripping, applying additional adhesive, or replacing any sections that do not meet the desired sealing standards.

By conducting a thorough test of the new weather stripping, you can identify and address any potential issues, ensuring that your car’s window is effectively sealed against external elements. This proactive approach will contribute to a more comfortable and secure driving experience, free from unwanted drafts, water leaks, and excessive noise.
