Attachment Style
The 2020 GMC Sierra 2500HD uses a J-hook attachment for both the driver and passenger side wiper blades. This is the most common and straightforward attachment type, making replacements quick and easy.
How to Install
- Lift the Wiper Arm: Gently pull the wiper arm away from the windshield until it locks in the upright position.
- Release the Old Blade: Locate the small tab on the underside of the J-hook connector where it meets the wiper blade. Press this tab to release the blade and slide it down and off the arm.
- Install the New Blade: Slide the new wiper blade onto the J-hook until you hear a distinct "click," indicating that it has locked securely into place.
- Lower the Arm: Carefully lower the wiper arm back onto the windshield.
Note: Always ensure the new blade is securely fastened before operating the wipers.
When to Replace
For optimal visibility and safety, you should replace your wiper blades every 6 to 12 months. You'll know it's time for a new set when you notice:
- Streaking: The blades no longer clear the windshield effectively, leaving streaks or bands of water.
- Chattering: The blade skips or vibrates across the glass instead of gliding smoothly.
- Squeaking: The wipers make an audible noise as they operate.
- Visible Wear: The rubber on the blade appears cracked, brittle, or worn.
