Windshield wipers can be an overlooked part of your car. If your wipers aren’t working properly, it can be difficult to see the road or other hazards when it rains or snows. Faulty wiper blades can be ineffective and even smear your windshield, potentially creating visibility issues. Fortunately, changing your wiper blades is a simple and typically inexpensive process that can be accomplished in 15 minutes or less on most modern cars. Also, simple, regular maintenance can help prolong the life of your wipers.
When should you replace your wiper blades?
It is recommended that you replace your wiper blades once a year to ensure they work effectively, according to AutoZone. However, it's essential to note that there are various types of wiper blades, and their lifespans may differ. You should also look for certain signs of wear and tear. For instance, if your blades smear dirty water, the blade’s edge is worn, or the blade makes a screeching sound when it wipes over the windshield, etc., then it may be time to replace them sooner.
Replacing your wiper blades
Changing your wiper blades is a relatively simple process on most cars. However, if don’t feel confident in your skills, you can always have a mechanic or dealership help you change them. If you don’t see any signs of wear and tear, you can have your windshield wipers checked when you go for an oil change. Here are the five steps to take if you decide to replace them on your own.
1. Determine the blade size
Measure each wiper blade length or check your owner's manual for the correct blade sizes, advises Kelley Blue Book (KBB). Sometimes blades themselves show the windshield wiper size but you can also ask an auto technician, if you’re not certain.
Windshield wiper sizes are typically expressed in millimeters, says Car and Driver. They note that windshield wipers are typically longer on the passenger side than the driver’s for visibility purposes. Blades that are too short will miss certain areas and blades too long may hit each other and cause damage.
2. Decide which type of wipers to get
Different blade types have different strengths, depending on the situation, explains AutoZone. But whether they’re conventional blades, beam blades, or a hybrid of the two, they’ll work on all makes and models. The right type of blade boils down to how much you’re comfortable spending, local climate and more.
Beam designs tend to be more expensive than conventional wipers, adds AutoZone. Conventional blades are made of a metal frame, while beam blades are entirely rubber which allows them to mold to the windshield’s curvature. Although more expensive, beam designs may have double the shelf life of a conventional blade.
3. Remove the old wipers
First, always consult your car manual – manufacturers vary in how blades are connected. Many vehicles have a tab that connects the blade to the arm, according to J.D. Power. Lift the wiper arm away from the windshield and depress the small tab on the underside of the wiper where it meets the wiper arm. Slide the wiper blade off the arm by pulling downward.
4. Attach the new wiper blades
Pull the wiper blade tight onto the arm. You will usually hear a clicking sound when it locks into place. Lower the arm slowly back onto the windshield and repeat this process on the other wiper arm.
5. Test them before driving
Run the wipers to see if they are working properly, advises Cars.com. It's better to do it now instead of finding out they aren't installed correctly during the middle of a downpour. You might even want to simulate rain with a hose or spray to ensure your new wipers are functioning properly.
Taking these simple steps can help make sure your wipers are working efficiently and help maximize your visibility for safer driving.
Inspect your wipers regularly
Wiper blades are made out of rubber that can wear out even with limited use. The blades should be inspected regularly and replaced, if needed. If your blades are cracked, torn or heavily worn, they might not grip the windshield properly and not fully remove mud, rain, sleet or snow. Wiper blades can take a beating during winter months, and since conditions and vehicles vary, you may consider checking your owner's manual and the information that comes with your wiper blades for guidance on maintenance.
Is windshield damage covered by insurance?
Having comprehensive coverage on your car insurance policy can help with fixing or replacing your windshield if it gets cracked or broken by a rock. There's another type of coverage called full glass coverage that might also be there to help cover the costs of fixing or replacing your windshield. With full glass coverage, too, you may not have to pay a deductible.
You can't always prevent windshield damage, but having the right coverage can help fix the problem and get you back on the road that much faster.
