Repair Guide for the Sound of a Car Wiper due to Sun Damage

One simple method to repair the SEAT ATECA windshield wipers, that can be done on any car model that uses similar front and rear wipers similar to the ones shown in the image. First, we disassemble the wiper brush from the vehicle. There is a rectangular piece that performs an anti-extraction function. Press the button and stretch the brush out.

We will use oil of the following product, they are utilities: 3-IN-ONE, Vaseline ointment, sewing machine oil, or WD-40 oil (This product is a spray, better to use liquid oil).

This is the most important step; IT IS IMPORTANT THAT THE RUBBER BAND OF THE WIPER IS NOT CRACKED OR TORN, IF IT IS, THIS PROCEDURE IS USELESS AND YOU MUST DISCARD THE WIPER

If the rubber band is in good condition, apply a thin layer of oil along both sides of the brush’s side band. Let it sit for 3 to 4 hours to absorb fully.

The rubber does not fully absorb the oil, only a small amount is absorbed. However, that’s enough to fix the noise caused by the rubber skipping on the glass when it does not slide properly.

Lastly, after 4 hours or even better, leaving it overnight after the application of oil, we dry it with a towel to remove all of the oil, now, we put more emphasis on both ends since if oil is left, it will stain the windshield when the wipers move over the glass.

If the window wiper is very dry after making the application, it is best to redo the process a second time and leave it overnight again.

Before replacing the windshield wiper arm, we will apply a little oil or Vaseline to the moving part of the clamp, which holds the blade, to avoid inflexibility.

Now that the wiper blade is replaced on the vehicle, we proceeded to examine by applying water to the window and activating the lever everything came out good about 85 out of 95% of the time, with the sound of the blade not sliding correctly on the windshield “ before it would bounce around in the process” now would be solved.

Or minimized greatly, if not, there is no choice but to replace the whole brush, but at least we would have tried in trying to replace and repair it.

With this simple exercise, we can extend the life of our windshield wiper blades from both the front and rear of the vehicle and solve the annoying noise they make when they do not slide correctly.

After some months, when they make noise again, I advise them to do the repair guide again and, as a precaution, you can apply up to 2 threads of oil to both sides of the rubber and let it absorb the oil overnight, and that should be enough and be elastic.

If you apply a third thread of oil like the ones in the photo and it's too much for the rubber to absorb, it is going to be wavy it is not going to make noise, but in its cleaning, you will see it improper cleaning and leaving gaps. This has been my experience hope it helps.
