Best aftermarket replacements

If you prefer to upgrade from the standard Mopar blades, there are several high-quality aftermarket options that perform exceptionally well on the Grand Cherokee's windshield. Here are the top picks organized by rough price tier:

• Bosch ICON (Premium): Widely considered the gold standard in the aftermarket. Their beam design provides even pressure and resists snow buildup.
• PIAA Si-Tech (Premium): Features silicone rubber that actively coats the windshield with a water-repellent barrier. Excellent longevity but comes at a higher price point.
• Rain-X Latitude (Mid to Premium): A very popular beam blade that applies a water-repelling coating as it wipes.
• Trico Force (Mid-Range): Specifically engineered with a swept-wing spoiler to maintain excellent contact at highway speeds, preventing wind lift.
• Michelin Stealth (Mid-Range): A great hybrid blade offering the flexibility of a beam blade with the structural support of a traditional frame.

Attachment style

The 2020 Jeep Grand Cherokee utilizes a Push-button attachment style for the front driver and passenger wiper arms (typically the standard 22mm top button). This makes swapping the front blades incredibly simple and tool-free.

The rear wiper blade features a specialized snap-in attachment (often referred to as a Roc Lock 3 style). It requires a bit of pivoting to release from the rear plastic arm housing.

How to install

Replacing the wiper blades on your 2020 Grand Cherokee is a quick DIY project. Follow these generic steps:

For the Front (Push-button):

1. Turn off the ignition and lift the wiper arm away from the windshield until it locks in the upright position.
2. Locate the small square button on the top of the wiper blade connector.
3. Press firmly down on the button and pull the blade straight out, sliding it away from the wiper arm.
4. Take your new blade and slide it directly into the arm until you hear a satisfying "click."
5. Gently lower the wiper arm back onto the glass.

For the Rear:

1. Carefully lift the rear plastic wiper arm away from the glass.
2. Rotate the wiper blade outward, away from the arm, until it snaps out of the C-shaped retaining clip.
3. Align the cross-pin of the new blade with the clip on the arm and press firmly until it snaps into place.

When to replace

For optimal safety, you should replace your wiper blades every 6–12 months. Sun exposure, freezing temperatures, and road debris degrade the rubber compound over time. You know it’s time for a replacement if you notice:

• Streaking or smearing across the field of view.
• Chattering or skipping as the blade drags across the glass.
• Squeaking noises during operation.
• Visible damage, such as tears or missing chunks of rubber on the blade edge.
