The replacement is a quick DIY task. For a 2018 Tucson, use the driver-side blade about 24 inches and the passenger-side blade about 18 inches, detach the old blades from the wiper arms, and snap on the new blades until they click securely. Replacing both blades at once helps maintain even wiping performance.
What you’ll need
Gather the correct replacement blades for your Tucson, typically 24" on the driver side and 18" on the passenger side. Some blades come with adapters to fit different arm styles (J-hook, pin, or bayonet). Check the packaging to confirm compatibility, and keep a clean workspace handy.
Step-by-step: removing the old blades
Before you remove the blades, power off the vehicle and lift the wiper arms away from the windshield so they stay in place. The Tucson uses standard blade connectors, but the exact release method depends on the arm and blade design. Use the release tab or lever on the blade to detach it from the arm.
- Turn off the engine and gently lift the wiper arm away from the windshield until it stays perpendicular to the glass.
- Locate the release mechanism on the blade connector (tab or button). Press or slide the release to free the blade from the arm.
- Slide the blade downward (or away from the arm, depending on the connector) to remove it from the wiper arm.
With the old blade removed, you’re ready to install the new one.
Step-by-step: installing the new blades
Before you install, verify the new blades match your arm’s connector type and length. Attach the blade so it sits securely on the arm, then lower the wiper back to the windshield and test for proper contact.
- If needed, attach the correct adapter to the blade to fit the Tucson’s arm (J-hook, pin, or other connector).
- Align the blade with the wiper arm and slide it onto the connector until you hear a click or feel it lock in place.
- Lower the wiper arm back onto the windshield so the blade rests properly against the glass.
- Repeat for the other blade if you’re replacing both sides.
- Test the wipers on a dry run, then with water to confirm even contact and streak-free performance. If streaks appear, reseat the blade or verify you have the correct blade type and length.
After installation and testing, your wipers should operate smoothly and improve visibility in rain or snow.
Summary
Replacing the wiper blades on a 2018 Hyundai Tucson involves removing the old blades by releasing the connector and installing new blades that match the arm type and lengths—typically 24" on the driver side and 18" on the passenger side. For best results, replace both blades at once and verify a secure click fit before testing the wipers.
