Fortunately, fixing squeaky windshield wipers is a relatively easy task that you can do yourself with a few simple tools and a little bit of time. In this article, we’ll walk you through the steps on how to fix squeaky windshield wipers, so you can get back to driving in peace and quiet.
Before you begin, it’s important to identify the source of the squeaking. In most cases, squeaky windshield wipers are caused by a lack of lubrication. However, there could be other underlying issues, such as worn-out wiper blades or a damaged wiper motor. Once you’ve identified the source of the problem, you can begin to take steps to fix it. If the squeaking is caused by a lack of lubrication, you can simply apply a small amount of silicone-based lubricant to the wiper blades. Be sure to wipe off any excess lubricant, so it doesn’t smear on your windshield. If the squeaking persists, you may need to replace the wiper blades. Worn-out wiper blades can become stiff and brittle, which can cause them to squeak when they’re in use. Replacing the wiper blades is a relatively simple task that you can do yourself with a few basic tools.
In some cases, squeaky windshield wipers may be caused by a damaged wiper motor. A damaged wiper motor may not be able to provide enough power to move the wiper blades smoothly, which can cause them to squeak. If you suspect that the wiper motor is damaged, you’ll need to take your vehicle to a mechanic for repairs. Attempting to repair a wiper motor yourself can be dangerous, so it’s best to leave it to a professional.
Identifying the Cause
Identifying the cause of squeaky windscreen wipers is essential for effective troubleshooting. Before jumping into repairs, it’s crucial to determine the underlying issue to address it precisely.
Several factors can contribute to wiper blade squeaking:
- Dry or Brittle Blades: Over time, the rubber compound on wiper blades can become dry and brittle. This reduces their flexibility and leads to excessive friction against the windshield, causing squeaking noises.
- Accumulated Debris: Dirt, dust, and other particles can accumulate on the wiper blades and windshield. When the blades wipe across the glass, these particles create a scraping noise, causing the characteristic squeak.
- Incorrectly Installed Blades: If wiper blades are not properly installed, they may not make full contact with the windshield. This can result in uneven wiping and produce squeaking sounds.
- Worn or Bent Wiper Arms: The wiper arms that hold the blades can become worn or bent over time. This can misalign the blades, causing them to rub against the windshield at an angle, leading to squeaking.
- Damaged Windshield: In some cases, the squeaking noise may be caused by a damaged windshield rather than the wiper blades. Chips, cracks, or scratches on the glass can create a rough surface that the blades catch on, resulting in squeaking.
To identify the cause accurately, inspect the wiper blades, windshield, and wiper arms thoroughly. Check for signs of wear, damage, or debris. Once the cause is identified, you can proceed with the appropriate troubleshooting steps.
Lubricating the Wiper Blades
Over time, the rubber on the wiper blades can dry out and become less effective at wiping away water. This can cause the blades to squeak when they’re in use. To fix this, you can lubricate the blades.
There are several different ways to lubricate wiper blades. One way is to use a silicone-based lubricant. You can also use a petroleum-based lubricant, but it’s important to note that petroleum-based lubricants can damage the rubber on the blades over time.
If you’re using a silicone-based lubricant, apply a small amount to a clean cloth and then wipe the blades down. If you’re using a petroleum-based lubricant, apply a small amount to the blades directly.
After you’ve lubricated the blades, test them out to make sure they’re working properly. If they’re still squeaking, you may need to apply more lubricant.
| Lubricant Type | Application |
|---|---|
| Silicone-based | Apply to a clean cloth and wipe blades down |
| Petroleum-based | Apply directly to blades |
Inspecting and Replacing Worn Blades
Worn wiper blades are a common cause of squeaky windshield wipers. Inspect your wiper blades for signs of wear, such as cracks, splits, or missing rubber. If the blades are damaged, they will need to be replaced.
To replace wiper blades, follow these steps:
1. Lift the wiper arm away from the windshield.
2. Locate the release button or lever on the wiper blade.
3. Press the release button or lever and slide the old wiper blade off the wiper arm.
