How To Replace Windshield Wipers

It's probably a good idea to check your wipers every six months. You probably won't want to wait until you can't see out of your windshield before changing your windshield wipers. In fact, most people end up waiting too long to do this basic car maintenance and have to change their wipers in the rain. If your wipers are beginning to show signs of wear, it's probably time to replace them. You can change them in just a few minutes.

Inspect your wipers: wipers should not be cracked, ragged, torn, or have any jagged edges. When they crack or tear, they become flimsy and cannot effectively remove water from your windshield.

Windshield wipers are nearly all built the same. An electric motor is connected to a metal wiper arm. The wiper arm extends over the windshield and holds the wiper blade tight against the windshield. The wiper blade is a metal and plastic device that holds a rubber insert.

If you live in an area that is prone to snow and ice, consider buying winter blades. These are more effective at removing snow and ice than normal all-purpose rain wipers.

1. Buy the new wipers. It's usually a good idea to change your windshield wipers at the parts store. You can take your old wipers off the car before you go into the store in order to compare the wipers before you buy them. At some parts stores, a salesperson may even help you install the new wiper blades in the parking lot. You'll have to decide whether you want to buy an entire wiper blade or just a refill. Each has its advantages. For instance, if the finish is wearing off the old wiper blade, then you may want to pay a little more for an entire wiper blade. However, if you want to spend a little less, you may want to opt for buying refills to change only the rubber part of the blade. It's usually easiest to replace the entire wiper blade.
2. Remove the old wipers. First, lift the wiper arm off of the windshield so that it is easier to work on. Then determine how your wiper blades are attached to the wiper arm. There are several different methods commonly in use today, but the general formula is still the same. Press or slide the release tab that connects the wiper blade to the wiper arm. Then pull firmly to separate the wiper blade from the wiper arm. The wiper may be easier to remove if it is perpendicular to the wiper arm. There are three different mechanisms commonly found on cars today.
   • The universal slide. This is the most common wiper blade design. You'll need to press the lever on the bottom on the connection, and then slide the wiper down towards the base of the wiper arm.
   • The side pin. The pin is made of a 7mm pin that is at a right angle to the wiper arm. You'll need to press the spring lock button with a small flathead screwdriver, and then pull the wiper blade away from the wiper arm.
   • The bayonet arm. Lift the locking lever, and then slide the wiper blade away from the base of the wiper arm. That is, slide the wiper blade away from the car.
3. Install new wipers. Follow the directions that come with your new wiper blades. It's usually a pretty simple process, and the directions are usually picture guides demonstrating how to install the wiper blade on your car. Most blades come with adapters to fit most any type of connector. Once again here are a few blade-specific instructions.
   
   
   • The universal slide. Place the blade just below the hook. Push the blade into the hook until it snaps into place.
   • The side pin. Press the hole onto the pin. It should lock automatically.
   • The bayonet arm. Lift the locking lever, and this time slide the wiper blade back down to the base of the wiper arm (slide it towards the car).
4. Test new wiper installation. Use your car's windshield mister to see that your wipers are working properly. They should operate smoothly without squealing, chattering or streaking.
