How to Replace Wiper Blades
Reviewed by GarageDex editorial
Replacing wiper blades is one of the easiest car jobs: about 5 minutes, no tools, and the only thing you really need is the right size. Most cars use two different lengths for the driver and passenger side. Here is the step-by-step, plus how to find your exact sizes.
Step by step
- Look up your exact driver and passenger wiper sizes (they are often different lengths).
- Lift the wiper arm away from the windshield until it locks upright.
- Press the release tab where the blade meets the arm and slide the old blade off the hook.
- Slide the new blade onto the arm until it clicks, matching the connector type.
- Gently lower the arm back to the glass and repeat for the other side.
The one thing that matters most
Get the sizes right. Many vehicles use a longer driver blade and a shorter passenger blade, and the connector (J-hook, pinch-tab, bayonet) has to match too. Look up the exact wiper sizes for your car before you buy.
Don't forget the rear
Many SUVs, hatchbacks, and wagons have a rear wiper that uses a different, shorter blade. If yours has one, replace it on the same schedule.
Frequently asked
How do I know what size wipers I need?
Driver and passenger blades are often different lengths (for example 26 inch and 19 inch). Look up your exact year, make, and model rather than guessing - the wrong length leaves streaks or hits the trim.
Do I need tools to change wiper blades?
No. Modern blades clip onto the arm by hand. Just be careful not to let the bare metal arm snap back against the glass while the blade is off - it can crack the windshield.
How often should wiper blades be replaced?
Every 6 to 12 months, or sooner if they streak, skip, or chatter. UV and ozone harden the rubber even if you rarely use them.
