Windshield Wiper Maintenance
Regular car maintenance is a must to keep you safe on the road. But between new tires, oil changes, brake inspections, and air filter replacements, it’s easy to overlook one (very) important component: windshield wiper upkeep.
You’re likely familiar with their function, but windshield wipers are operated by an electric motor to remove rain, snow, ice, and debris from a car’s front and, in some models, back windows. If they’re not working correctly, it can be difficult to see the road and other hazards when inclement weather strikes.
Fortunately, windshield wiper care and maintenance are relatively easy when you know what you’re doing.
Regularly Clean Your Windshield
Windshield wipers wear down quickly if they’re constantly wiping gritty, dirty glass. To prolong the wear, clean your car’s windshield every couple of weeks. Most gas stations have a free squeegee available, so take advantage of it.
Reposition the Blades
If you’re expecting freezing temperatures, pull the wiper blades away from the windshield the night before. This prevents the blade’s rubber from freezing to the glass and makes it easier to scrape away frost.
Always Defrost
If you forgot to pull the blades away from the glass before a freeze, no worries. Just be sure to thoroughly defrost your car before turning them on so they don’t stick to the windshield. Wipers can also snap if they’re trying to push a heavy load, so scrape away excess ice and snow when necessary.
Use Wiper Fluid
Wipers are designed to push away water on a slick surface. Operating them on dry glass can cause unnecessary wear on the blades and even scratch the glass due to excessive friction. If you’re trying to wipe away pollen or excess buildup on a dry day, be sure to spray windshield wiper fluid.
Signs You Need New Windshield Wipers
Most car dealerships recommend replacing your windshield wipers once or twice a year, depending on the climate and frequency of use, but the following signs indicate it’s time to invest in a new pair.
- Smears or streaks on your windshield
- Unusual noises when in use, such as squeaking or scraping
- A bent wiper blade
- Peeling rubber
- Uneven wiping
- Inadequate visibility, even when in use
How to Replace Windshield Wipers
Your local auto shop can assist in windshield wiper replacement, but it’s relatively quick and straightforward to do it yourself. Here’s a step-by-step guide:
1. Determine the length of your windshield wipers by measuring both blades. Alternatively, you can consult your car’s owner manual for blade specifications.
2. Different blades have different strengths, so purchase a pair that suits your needs. The most common are conventional blades, beam blades, or a hybrid of the two.
3. Ensure your car is off, then lift the arm of the wiper away from the windshield so it remains fully extended.
4. Press the small tab or button on the bottom of the wiper while you slide the old wiper blade off the arm by pulling downward.
5. Attach the new wiper blade by pulling the blade tight onto the arm. You should hear a clicking sound when it locks into place.
6. Lower the arm back to the glass and repeat the process on the other side.
7. Run the wipers to ensure they’re working properly.
Before you take your vehicle for a servicing, review which other basic maintenance items you can complete yourself.
