New Wiper Blades vs Refills (Our Advice)

Most BMW models allow you to replace the rubber insert (aka refills) rather than the entire wiper blade. However, while this can work out cheaper slightly than buying the entire blade, inserts are tricky to install and are becoming increasingly difficult to find.

These days, most people simply replace the entire blade. Aftermarket brands like Rain-X or Bosch produce excellent blades that are much easier to fit and we find provide better visibility than only replacing the rubber insert.

How To Change BMW Windshield Wiper Blades

To install a new set of wiper blades on your BMW, follow these simple instructions:

1. Remove the old wiper blade: Lift the driver’s side wiper blade arm away from the windshield and then press the tab or button that holds the wiper blade in place to release the old blade.

   

2. Slide on the new wiper blade: Align the new wiper blade with the wiper arm and slide it onto the arm until it clicks into place.

   

3. Secure the new wiper blade: Snap the new blades cap down to secure the wiper blade in place.

   

4. Repeat the process for the passenger’s side blade.
5. Test the wipers: Once the new wiper blades are installed, test the wipers by turning them on and making sure that they are working as intended.

If you’re finding it hard to fit the wiper blades yourself, we recommend asking a friend or family member with auto experience to help.

Windshield Wipers FAQs

Below we answer some of the most frequently asked questions about changing windshield wiper blades.

When Should You Replace Windshield Wiper blades?

Wiper blades should be replaced every 12-24 months or as soon as they start to show signs of wear and tear. The right time to replace your wipers will be different for everyone depending on factors such as the climate where you live and how often you use your car.

Some common signs that your wipers need to be replaced include:

1. Streaks or smears on the windshield: If the wipers leave streaks or smears on the windshield, it could be a sign that the blades are worn or damaged.
2. Noise: Wiper blades that make noise when in use, such as chattering or squeaking, may be in need of replacement.
3. Visible damage: If the wiper blades are torn, frayed, or otherwise visibly damaged, they should be replaced.
4. Poor performance: If the wipers are not cleaning the windshield effectively, it could be a sign that the blades are worn and need to be replaced.

How Important Is It To Use The Correct Wiper Blade Size?

Buying the correct wiper blade size is very important. Here’s why:

• You’ll be safer – If you purchase the wrong size wiper blades (too big or too small), your car won’t be able to clear the rain from your windshield effectively, and your visibility will be reduced.
• You’ll Prevent damage to your car – If you buy a blade that’s too big, it can put too much pressure on the wiper motor, while blades that are too small don’t often make enough contact with the windshield, which can damage the wiper blade arms.

Are Wiper Blades Universal In Size?

Windshield wipers are not universal. Just like cars, wipers come in various shapes and sizes. Manufacturers make wiper blade dimensions specific to the car to ensure that they can clear the windshield effectively.
