2020 GMC Yukon Wiper Blade Sizes & Replacement Guide

Maintaining clear visibility is critical for safe driving, especially in a large SUV like the 2020 GMC Yukon. Whether you are driving through heavy rain, snow, or dusty conditions, having fresh, properly sized wiper blades ensures your windshield stays clear. Below is a comprehensive guide to finding the right wiper blade sizes, attachment types, and replacement procedures for your 2020 GMC Yukon.

Quick reference

For the 2020 GMC Yukon, the driver and passenger side wiper blades are the same length. It is highly recommended to replace all three blades (including the rear) at the same time for consistent performance.

(Note: Always verify exact OEM part numbers with your local GM parts counter using your VIN, as specific trim levels or mid-year production changes can occasionally alter requirements.)

Best aftermarket replacements

If you prefer to upgrade from the standard factory blades or want a quick replacement at your local auto parts store, several premium aftermarket brands offer exact-fit replacements for the 2020 GMC Yukon.

• Bosch ICON: (Premium Price) These beam-style blades are a favorite for their extreme weather durability and aerodynamic design that resists wind lift at highway speeds.
• Rain-X Latitude: (Mid to Premium Price) Features a water-repelling coating that transfers to your windshield to help water bead up and roll off.
• Trico Force: (Mid-Range Price) A robust high-wind beam blade designed with a swept-wing spoiler to ensure excellent glass contact.
• Michelin Stealth: (Mid-Range Price) Hybrid technology that combines the flexibility of a beam blade with the sturdy construction of a traditional frame.
• PIAA Si-Tech: (Premium Price) Uses advanced silicone rubber rather than traditional organic rubber, providing exceptional longevity and continuous water-repellent performance.

Attachment style

The front wipers on the 2020 GMC Yukon utilize a Push-button (19mm) attachment style, which is very common on modern General Motors vehicles. This modern design is incredibly secure and much less prone to freezing or jamming compared to older J-hook styles. The rear wiper uses a vehicle-specific custom snap-in (or Roc Loc 3) attachment designed to sit flush against the rear glass and fit under the specialized rear wiper arm cover.

How to install

Replacing the push-button front wiper blades on your Yukon is a straightforward process that takes just a few minutes:

1. Lift the wiper arm: Pull the wiper arm away from the windshield until it locks in the upright position.
2. Remove the old blade: Locate the square push-button on the top of the wiper blade connector. Press this button firmly down while pulling the blade away from the wiper arm.
3. Attach the new blade: Align the connector of the new blade with the end of the wiper arm. Slide it directly into the arm until you hear a distinct "click," indicating the push-button has locked into place.
4. Test: Gently lower the arm back to the glass. Turn on the ignition and test the wipers with washer fluid to ensure they are secure and functioning smoothly.

Note for the rear blade: The rear wiper often requires you to gently lift the plastic base cover to rotate the arm fully outward. Snap the old blade out of its central pivot pin, and press the new 11-inch blade firmly until it snaps into the locking groove.

When to replace

For optimal safety, industry experts recommend replacing your wiper blades every 6–12 months. However, you should replace them immediately if you notice any of the following symptoms:

• Streaking or smearing water across the windshield instead of clearing it.
• Chattering or squeaking noises as the blades drag across the glass.
• Skipping over sections of the windshield.
• Visible tearing, splitting, or dry-rotting of the rubber squeegee edge.
