Why Doesn't the Wiper Clean Properly?
2 Answers
If the wiper doesn't clean properly, it may be due to incorrect positioning or the need to replace the rubber strip. Below is relevant information about wipers: 1. Wiper switch position: The wiper switch for most vehicles on the market is located on the right-hand stalk behind the steering wheel, typically in a stalk-style design. Similar to the light stalk, the wiper stalk has various function symbols printed on it. Although the symbols and their positions may vary between brands, the functions are generally similar. 2. How to use the wiper: Icon – Manual operation. Push the stalk upward, and the wiper will start working continuously. Release the stalk, and it will automatically return to its original position, stopping the wiper. Suitable for clearing small amounts of water or debris from the windshield. OFF – The front wiper stops working. INT – Automatic intermittent operation. Pull the stalk down one notch, and the wiper will start working intermittently. This setting requires manual resetting and is suitable for light rain or snow. LO – Continuous operation. Pull the stalk down another notch, and the wiper will operate continuously at a steady rate. This setting also requires manual resetting and is suitable for heavier rain or snow. HI – Continuous high-speed operation. Pull the stalk all the way down, and the wiper will operate at high speed. This setting requires manual resetting and is suitable for heavy rainstorms.
It's really annoying that my car's wipers aren't cleaning properly. The main issue is the aging wiper blades—the rubber hardens and cracks over time, losing tight contact with the glass. The oily film on the windshield is also troublesome, especially when parked under trees or near kitchens, as grease and dirt cause the wipers to skip. Additionally, if the wiper arm springs loosen and don't press firmly against the glass, many areas will be missed. Summer sun accelerates blade deterioration, while winter ice can easily crack them. I recommend wiping the blades with a damp cloth monthly to remove dust and extend their lifespan. Replacing the blades isn't expensive and can be done DIY—just remember to choose silicone material for better durability.
