In short, replacing the wiper blades on a 2021 Tucson is a straightforward DIY task: lift the wiper arms, release the old blades from their adapters, snap in the new ones, and test the sweep. Front blades are typically around 26 inches on the driver side and about 16–17 inches on the passenger side, with a rear blade of roughly 12 inches. Confirm exact sizes on the blade packaging or in the owner’s manual before purchasing.
What you’ll need
Before you start, gather the right blades and basic supplies to ensure a smooth swap. This guide covers front and rear blade replacement for the Tucson.
- Replacement wiper blades compatible with the 2021 Tucson (front driver, front passenger, and rear blade).
- A clean, dry cloth to wipe the blade area and prevent dirt from getting on the new blades.
- Optional: a small flathead screwdriver or blade-release tool if your model uses a stubborn connector.
- Gloves or a sleeve to protect your hands and windshield while handling blades.
With the right blades and a clean work area, you’re ready to perform the swap. Always verify layout and size from the packaging or the owner’s manual if you’re unsure of the exact lengths for your vehicle’s trim level.
Replacing the front wiper blades
The front blades on a Hyundai Tucson attach to the wiper arms with a straightforward release mechanism. The process is similar for most modern vehicles, but blade adapters can vary. Follow these steps to ensure a secure fit and proper sweep across the windshield.
- Lift the wiper arm away from the windshield until it stays in a raised position.
- Locate the release tab or locking clip on the blade where it connects to the wiper arm.
- Depress the release tab (or operate the clip) and slide the old blade downward away from the arm to remove it.
- Check the new blade for the correct connector type. Align the new blade with the wiper arm’s connector and slide it into place until you hear or feel a click, confirming a secure attachment.
- Gently lower the wiper arm back against the windshield and repeat with the other front blade if needed.
- Test the wipers with the ignition on and the wipers set to a low speed to ensure even contact and proper sweep across the glass.
Concluding: Once the front blades are engaged and tested, the windshield should clear evenly with no skipping or streaking. If you notice any obstruction or uneven contact, recheck the blade installation and connector alignment.
Replacing the rear wiper blade
The rear blade on the Tucson uses a simpler attachment, but the exact method can vary by trim. Here are the general steps you can follow to replace the rear blade safely and correctly.
- Open or lift the rear hatch as needed to access the rear wiper arm and blade.
- Rotate the blade housing or release mechanism to expose the connector. Some designs require a small turn (about 90 degrees) or a squeeze of a release tab.
- Remove the old blade from its adapter by pulling it straight away from the arm or releasing the locking mechanism according to the blade model.
- Align the new rear blade with the adapter on the wiper arm and insert until it locks in place.
- Return the rear wiper arm to its resting position and test by activating the rear wipe cycle to ensure a clean sweep.
Concluding: The rear blade swap completes the job. If the new blade doesn’t seat securely, double-check that you’re using a blade compatible with your Tucson’s rear wiper connector and that the locking mechanism is fully engaged.
Tips for best results
To maximize performance and blade life, consider these practical tips. Ensure you clean the blade edges and windshield before testing, replace blades every 6–12 months (more often in harsh climates), and avoid using blades on a dry windshield, which can wear the rubber unevenly. If you have rain-sensing wipers or a specialized blade design, consult the blade packaging or dealer guidance to confirm the correct adapter and installation steps.
Safety and maintenance notes
Handle the wiper arms gently when lifting and lowering, as they can snap back and damage the windshield if released abruptly. Always dispose of old blades properly and store replacement blades in a clean, dry area until installation. Periodically inspect blade edges for nicks or cracks, and wipe away any remaining debris from the blade frame to prevent future streaking.
Summary
Changing the wiper blades on a 2021 Hyundai Tucson is a straightforward DIY task. Start with the front blades, using the release mechanism to detach the old blades and snap in the new ones, then move to the rear blade and repeat. Confirm blade sizes and adapter compatibility before purchase, test the sweep after installation, and follow basic maintenance tips to extend blade life.
