Replacing a rear wiper blade takes 5 to 10 minutes and requires no tools beyond what comes in the box

A rear wiper blade wears out like a front blade — the rubber hardens, streaks appear, or the blade skips across the glass. Replacing it yourself costs $15 to $40 for the blade and takes longer to drive to the store than to install it. You do not need a mechanic, and you do not need special tools.

The process is nearly identical to replacing a front blade, except the arm is usually smaller and the release mechanism may differ slightly depending on your vehicle's make and model. This guide walks you through the standard steps, then covers the variations you might encounter.

Key Takeaways

  • Most rear wiper blades cost $15 to $40 and snap or slide onto an arm that you can access from inside the hatch or trunk.
  • The blade release mechanism is usually a small tab, clip, or button — pushing or sliding it frees the blade from the arm in seconds.
  • Buying the correct blade for your vehicle requires your year, make, and model; auto parts stores can look this up for you or you can check your owner's manual.
  • The entire replacement takes 5 to 10 minutes and requires no tools beyond what may come packaged with the new blade.
  • If the arm itself is bent or the motor does not move the blade, the repair is beyond blade replacement and requires a mechanic.

Identify your rear wiper blade type before you buy

Rear wiper blades come in two main styles: hook-end (also called bayonet) and side-pin. The hook-end blade has a notch that catches onto a hook at the end of the wiper arm. The side-pin blade has a pin hole on the side that slides onto a pin sticking out from the arm. A few vehicles use a third style called top-lock, where the blade locks down from above.

You do not need to memorize which type yours is. When you buy a replacement blade at an auto parts store, give the staff your vehicle's year, make, and model, and they will hand you the correct one. If you are ordering online, the product page will specify the type and confirm it fits your vehicle. Your owner's manual also lists the correct blade size and type.

Do not assume your rear blade is the same size as your front blades — many vehicles use a smaller rear blade. Buying the wrong size will not fit the arm.

Locate the rear wiper arm and release the old blade

Open your hatch or trunk and look at the rear window. The wiper arm extends from the bottom or side of the window frame. On most vehicles, you can access it without removing any panels — it straightforward swings out into the open hatch or trunk space.

Lift or pull the wiper arm away from the window to give yourself room to work. The arm will move freely — it is not locked in place. Once the arm is clear of the glass, locate the release mechanism on the blade itself. This is usually a small tab, clip, or button where the blade connects to the arm.

Push, slide, or press the release mechanism according to the type. For a hook-end blade, you may need to slide the blade backward along the hook. For a side-pin blade, you typically push a small tab to release the pin. For a top-lock blade, you push down on a latch at the top of the blade. The blade will come free in one or two seconds. Set the old blade aside.

Install the new blade onto the arm

Take the new blade out of its packaging and inspect it for any damage. Do not remove any protective coating or film yet — some blades ship with a plastic cover that you peel off after installation.

Align the new blade with the arm. If it is a hook-end blade, slide it forward onto the hook until you hear or feel a click. If it is a side-pin blade, line up the pin hole and press the blade down onto the pin until the clip or latch snaps into place. If it is a top-lock blade, lower the blade onto the arm and press the latch down until it locks.

Tug gently on the blade to confirm it is seated firmly. It should not slide or rotate on the arm. If it feels loose, remove it and try again — the connection may not be fully seated.

Test the wiper and lower the arm

Close the hatch or trunk and sit in the driver's seat. Turn on the rear wiper using the control on your steering column or dashboard. Watch the blade move across the glass. It should sweep smoothly without skipping, chattering, or leaving streaks. If it does any of those things, stop and check that the blade is seated correctly on the arm.

If the blade is installed correctly but still performs poorly, the arm itself may be bent or the motor may be failing — both are beyond a blade replacement and require a mechanic. If the blade performs well, you are done. The new blade is ready to use.

What to do if the blade does not fit or the arm will not move

If you bought the wrong blade size, it will not align with the arm or will be too loose once installed. Return it to the store and confirm your vehicle's year, make, and model with the staff. They can verify the correct size and swap it for you.

If the wiper arm will not move away from the window or feels stuck, do not force it. The arm may be frozen by rust or the motor may be failing. Forcing it can bend the arm or break the motor. Stop and take the vehicle to a mechanic instead.

If the blade snaps or cracks during installation, it was likely damaged in shipping or was defective. Return it to the store for a replacement — this is covered under the manufacturer's warranty.

Frequently Asked Questions

How often should I replace my rear wiper blade?

Rear wiper blades typically last 6 to 12 months depending on climate and how often you use them. If you live in a dry climate and rarely use the rear wiper, it may last longer. If you live in a wet climate or use it frequently, replace it sooner. Replace it whenever it streaks, skips, or leaves areas of the glass uncleaned.

Can I replace just the rubber insert instead of the whole blade?

Some blade designs allow you to replace only the rubber refill, which costs $5 to $15. However, most rear wiper blades are not designed this way — the rubber and frame are one unit. Check your blade's packaging or ask at an auto parts store whether a refill is available for your specific blade model.

What if my vehicle does not have a rear wiper?

Not all vehicles come with a rear wiper. Sedans and coupes rarely have them, while hatchbacks, SUVs, and wagons usually do. If your vehicle does not have one, there is nothing to replace. If you want to add one, that is a modification beyond this guide and requires a mechanic.

Do I need to turn off the ignition before replacing the blade?

It is safer to turn off the ignition and remove the key before you start. This prevents the wiper from moving unexpectedly while your hands are near the arm. Some vehicles allow you to park the wiper in a raised position using a menu option — check your owner's manual if your vehicle has this feature.

What if the wiper arm itself is bent?

A bent arm will not hold the blade at the correct angle and the wiper will not clean properly. Do not try to bend it back yourself — you can crack the arm or damage the motor. Take the vehicle to a mechanic to have the arm replaced or straightened.
