The 2020 Jeep Wrangler is known for its rugged build and off-road capability. But even the toughest vehicle needs the right wiper blades to keep your view clear in rain, snow, and mud.
Choosing the correct size for your wiper blades is more important than many drivers realize. The wrong size can mean poor visibility, scratched glass, and even damage to your wiper system.
This guide will help you understand exactly which sizes you need for your 2020 Jeep Wrangler, how to choose quality blades, and what mistakes to avoid.
Wiper Blade Sizes For 2020 Jeep Wrangler
The 2020 Jeep Wrangler uses two different wiper blade sizes for the front windshield and a different size for the rear (if equipped with a rear wiper).
- Driver’s Side: 18 inches
- Passenger’s Side: 18 inches
- Rear Wiper (if your model has one): 12 inches
Both the driver and passenger sides use the same 18-inch blades. This is not always the case with other vehicles, so it’s a small but helpful detail. The rear wiper is less common and only found on certain trims, such as the Wrangler Unlimited.
Why Wiper Blade Size Matters
A blade that’s too long can hit the edge of your windshield, causing noise and less coverage. Too short and you’ll leave large areas uncleared, making it hard to see. The right size ensures maximum contact and efficient clearing of your windshield.
Some drivers think a bigger blade will always be better. But for the Wrangler’s upright windshield and unique design, sticking to the factory-recommended size is the best choice. Using the wrong size may also void the warranty on your wiper system.
Comparing Wiper Blade Options
You’ll find different types of wiper blades in auto stores and online. Here’s a simple comparison of the most common types for the 2020 Jeep Wrangler:
| Blade Type | Performance | Lifespan | Cost |
|---|---|---|---|
| Conventional | Standard wiping, basic design | 6-9 months | Low |
| Beam | Better contact, handles snow/ice well | 12+ months | Medium to high |
| Hybrid | Mix of conventional and beam strengths | 12+ months | Medium |
For most Jeep Wrangler owners, beam blades offer the best balance of durability and performance, especially if you drive in tough weather.
How To Replace Your Jeep Wrangler’s Wiper Blades
Changing your wiper blades is simple and can save you money. Here are the steps:
- Lift the wiper arm away from the windshield.
- Press the small tab where the blade meets the arm.
- Slide the old blade off.
- Align the new blade and slide it into place until it clicks.
- Gently lower the arm back onto the windshield.
Always check that the new blade is secure before driving. Some drivers forget this, and the blade can come loose in heavy rain.
When To Replace Wiper Blades
You should check your blades every six months. Replace them if you notice:
- Streaking or smears on the glass
- Chattering sounds
- Cracks or splits in the rubber
- Reduced contact with the windshield
A good tip is to replace your wipers at the start of spring and fall. Extreme temperatures wear out rubber faster than you might expect.
Oem Vs. Aftermarket Wiper Blades
OEM (Original Equipment Manufacturer) blades are made by Jeep or its partners. They match your vehicle’s specs exactly.
Aftermarket blades are made by other companies and may fit many vehicles.
Here’s a comparison to help you decide:
| Feature | OEM Blades | Aftermarket Blades |
|---|---|---|
| Fit | Guaranteed | Usually good, not always perfect |
| Price | Higher | Lower to medium |
| Variety | Limited | Wide range |
For most drivers, quality aftermarket blades from brands like Bosch or Rain-X are as reliable as OEM, and often more affordable.
Common Mistakes When Buying Wiper Blades
- Guessing the size: Always check your owner’s manual or measure your old blades.
- Mixing blade types: Using different types on each side can cause uneven cleaning.
- Ignoring the rear wiper: If your Wrangler has one, it’s just as important as the front blades.
- Buying cheap blades: Low-cost options often wear out quickly and can leave streaks.
A common insight is that many stores offer free wiper installation if you buy in person. Take advantage of this service if you’re not comfortable changing blades yourself.
How Weather Affects Your Wiper Blades
The 2020 Jeep Wrangler is built for all kinds of weather, but your wiper blades need regular care. Hot sun can make rubber crack, while snow and ice can make blades stiff or torn.
Consider winter-specific blades if you live in a cold climate. They have extra protection against freezing and will last longer.
