There are several ways that wiper blades are in installed on cars especially on older cards. So how do you know when it is time to replace your blades. First thing don’t wait until they do not work any longer before you replace them. Because the time you are going to need the most is when you will find out they are needing to be replaced. So what are the signs that your wipers need to be replaced. Examine the wipers for cracks. Old windshield wipers become hard and cracked over time, especially in cold climate like here in Cincinnati. If your wiper seems to have lost it’s rubbery spring, it’s probably time to replace it. Pay attention next time it rains. If your wipers leave streaks of water across your windshield that aren’t much easier to see through than pounding rain, their rubber has probably lost its grip.

Wiper blades are made of rubber, so they naturally wear out after several months of wiping snow, rain and dust from your windshield. That salty mist that we get from treated roads is very damaging to wiper blades. You could take your car to the mechanic to have them changed, but it’s just as easy to change them yourself. The fitting process is identical for the vast majority of cars on the road.
Windshield wipers are made with three basic parts: the lower wiper arm that extends from the base of the windshield, the metal blade attached to the lower arm, and the rubber blade that actually wipes the windshield. When your windshield wiper blades, you’re really only changing the rubber blades that get worn down by water and inclement weather.
Buy replacement blades. To find out what size replacement blades you need, measure the old rubber blades using a ruler or measuring tape. Write down the exact measurements, then go to an auto parts store and buy rubber blades in those exact sizes.Don’t assume that the left and right wiper take the same size blade. One side is often an inch or two shorter than the other. Wiper blades usually run about $15-$20 each. You’ll save the cost of labor by installing them yourself.
Raise the metal wiper arm away from the windshield. It should be able to hold steady in a position off of the windshield. Be careful with the positioning because the metal wiper arm is spring-loaded, and it could snap back and crack your windshield.
Unhook the old wiper blade. Look at the joint where the rubber wiper blade meets the metal arm. There should be a small plastic stopper holding the blade in place. Press the stopper and unhook the old wiper blade to separate it from the metal arm.Some wiper blades have pins to hold the rubber wiper in place, rather than a hook.Make sure one hand is holding the wiper away from the windshield during this entire process.You may want to protect your windshield with a folded towel, just in case you the arm snaps back while you’re trying to change the wiper.
Insert the new wiper. Slide the refill wiper into the same end of the arm where you pulled the old wiper out. Gently pivot the new wiper until the hook snaps into place to secure it. Lay the wiper back against the windshield.
Repeat with the second wiper. The procedure is exactly the same for replacing the second wiper. Just make sure you use the correct size for each side.
