BMW 750i Wiper Blade Insert
How to Diagnose BMW 750i Wiper Blade Insert Problems
Your BMW 750i wiper blade insert is a very essential component that keeps you safe when driving on rainy and snowy days. Without it, you won't be able to see the road clearly. But overtime, the rubber insert becomes severely damaged. When this happens, you'll experience a series of problems. To determine the culprits behind these wiper blade insert-related issues, simply follow these troubleshooting steps:
Noise is one of the most common problems experienced in a wiper blade insert. When the squeaky sound becomes too loud, you and the other passengers in your vehicle will notice it right away. If you want to examine the blade insert further, observe your wipers while you're standing outside your car. If the sound gets even louder, it's time to examine your rubber blades. First, check if the blades are installed properly. Each rubber filler must be fitted snugly inside the channel. After this, lift the wiper blade, and keep it in upright position. Carefully inspect each blade for dirt build up. When the rubber blade is full of dust and grime, it won't glide smoothly on the windshield. It's the reason why you hear the annoying squeaky sound when your wipers are moving.
If you noticed that one of your wiper blade inserts is missing, you should check the condition of the wiper channels right away. When the channels of the wiper assembly are extremely corroded, they won't be able to secure the blade inserts firmly. To troubleshoot, lift the wiper arm from the windshield. Find the two clips on each side of the blade. If you see that the clips are damaged, you might need to replace not just the blade inserts but the wiper assembly as well.
A slow-moving wiper is really irritating. It can also lead to serious road accidents because you won't be able to see the road ahead. When you keep on experiencing such problem, check the speed that you've set for your wipers first. It's possible that the control is set to minimum speed. If the wiper is still moving slowly, it's time to check the rubber blade inserts. The rubber filler can get stiff especially when the temperature is cold. Add an anti-freeze product to your windshield cleaner to prevent your wiper blade inserts from freezing.
