Jeep Grand Cherokee Rear Window Wiper Replacement Guide
Reading Time: 7 minutes The Jeep Grand Cherokee is a popular SUV known for its strong performance, comfort, and off-road abilities. For many owners, the rear window wiper may not seem important—until you drive in rain, snow, or dusty conditions. This simple part keeps your rear view clear and safe. Yet, many drivers do not know how it works, how to maintain it, or what to do when it stops working. This guide will help you understand everything you need about the Jeep Grand Cherokee rear window wiper in a clear, step-by-step way.
Why The Rear Window Wiper Matters
Driving an SUV like the Grand Cherokee means you often face mud, rain, and snow. The rear window is large, so it collects water and dirt easily. Without a working rear window wiper, your visibility drops. This is not just an inconvenience—it’s a safety risk. Good visibility helps you:
- Change lanes safely
- Reverse with confidence
- Spot hazards quickly
Many accidents happen because drivers cannot see well behind them. The rear wiper, though small, plays a big role in keeping you safe.
How The Rear Window Wiper Works
The rear window wiper system is simple but effective. Here’s how it operates:
- Wiper arm: Holds the wiper blade and moves across the glass.
- Wiper blade: The rubber part that touches the glass and clears water and debris.
- Wiper motor: Powers the movement of the arm.
- Washer nozzle: Sprays cleaning fluid to help remove dirt.
When you turn on the wiper switch, the motor moves the arm back and forth. The washer nozzle can spray fluid to help clean stuck dirt or ice.
Typical Features In Grand Cherokee Models
Most modern Grand Cherokees (2011-present) have:
- Intermittent wiper settings
- Rear washer spray button
- Automatic shut-off when the window is opened
Older models (before 2010) may have basic on/off operation. Check your owner’s manual for details.
Common Problems And Quick Fixes
Even simple systems have issues. Here are the most frequent problems with the Jeep Grand Cherokee rear window wiper:
- Wiper does not move: Usually a faulty motor, blown fuse, or broken switch.
- Wiper moves slowly or stops mid-way: Often caused by a weak motor or debris blocking the arm.
- Wiper blade leaves streaks: Blade is worn or dirty.
- Washer fluid does not spray: The nozzle is clogged or the fluid reservoir is empty.
Troubleshooting Steps
- Check the fuse box (see the owner’s manual for location).
- Listen for the motor—no sound may mean an electrical issue.
- Inspect the wiper arm for bends or blockages.
- Clean or replace the blade if streaks appear.
These easy checks solve most basic problems.
How To Replace The Rear Wiper Blade
Replacing the wiper blade is simple and takes less than 10 minutes. Here’s how:
- Buy the correct size: Most Grand Cherokees use a 12-inch rear wiper blade.
- Lift the wiper arm: Gently pull the arm away from the glass.
- Release the old blade: There is usually a small clip—press it and slide the blade out.
- Attach the new blade: Slide it in until you hear a click.
- Lower the arm: Place it back on the glass gently.
Example: Step-by-step Replacement
A new 12-inch blade costs about $10–$20. You do not need special tools. Avoid buying blades that are too long—they can hit the window trim and wear out faster.
Rear Wiper Motor Replacement: What To Expect
The wiper motor usually lasts many years, but it can fail from heavy use or water damage. Signs you need a new motor:
- Wiper does not move at all
- Clicking or grinding noises from the rear hatch
- Wiper stops in the wrong position
Cost And Labor
- Motor price: $50–$120 (aftermarket or OEM)
- Labor: 30–60 minutes for a mechanic
If you are handy, you can replace it yourself with a socket wrench and screwdriver. Be careful: disconnect the battery before working with any electrical parts.
Comparison: Rear Vs. Front Wipers In The Grand Cherokee
Many people wonder if the rear wiper is as important as the front. Here’s a side-by-side look:
| Feature | Front Wiper | Rear Wiper |
|---|---|---|
| Size | 18–24 inches | 12 inches |
| Usage Frequency | High | Medium |
| Replacement Cost | $15–$40 (pair) | $10–$20 (single) |
| Impact on Safety | Critical | Important |
Both are important. Never ignore the rear wiper—it helps prevent surprises on the road.
Choosing The Right Rear Wiper Blade
Not all blades are the same. Here’s what matters:
- Fit: Always check the correct length and attachment style. Most Grand Cherokees use a “hook” or “pinch tab” connector.
- Material: Rubber is standard, but silicone blades last longer.
- Brand reputation: Stick to known brands like Bosch, Rain-X, or OEM Jeep parts.
Example Comparison Of Popular Rear Wiper Blades
| Brand | Material | Lifespan | Price |
|---|---|---|---|
| Bosch | Silicone | 12–18 months | $15 |
| Rain-X | Rubber | 6–12 months | $12 |
| OEM Jeep | Rubber | 12 months | $18 |
A silicone blade may cost more, but lasts longer and works better in extreme weather.
Maintenance Tips For Long Life
To keep your rear window wiper working well:
- Clean the blade with a damp cloth every month.
- Check for cracks or splits in the rubber.
- Fill the washer fluid with a winter mix to prevent freezing.
- Lift the blade off the glass before scraping ice.
Twice a year, check the wiper during your regular car wash. Avoid using the wiper on dry glass—it wears out the rubber quickly.

Real-world Example: Winter Driving In Colorado
Emily owns a 2017 Grand Cherokee in Denver, Colorado. In winter, her rear window gets covered in snow and road salt. She found her wiper left streaks and sometimes froze to the glass. After replacing her blade with a silicone model and using winter washer fluid, the problem was solved.
Emily now checks her rear wiper every fall and spring. This simple habit saves her time and keeps her safer on icy roads.
When To Call A Professional
Some problems need expert help:
- Rear wiper motor keeps failing (could be wiring issue)
- Wiper arm is bent or damaged
- Rear hatch or glass does not open after wiper use
A certified Jeep mechanic can diagnose deeper electrical or mechanical issues. Delaying repairs can cause more costly damage.
Common Mistakes Jeep Owners Make
Many new owners forget about the rear wiper until it fails. Here are mistakes to avoid:
- Using the wrong blade size (causes poor wiping or damage)
- Ignoring streaks or skipping (means the blade is worn)
- Using the wiper to clear thick ice (can burn out the motor)
- Not cleaning the nozzle (leads to clogs)
Checking the rear wiper every season prevents bigger issues later.

Frequently Asked Questions
How Often Should I Replace My Jeep Grand Cherokee Rear Wiper Blade?
Most experts recommend changing the rear wiper blade every 12 months. If you notice streaks, noise, or the blade looks cracked, replace it sooner. Harsh weather can wear out blades faster.
Can I Use A Regular Front Wiper Blade On The Rear Window?
No, you should use a blade made for the rear wiper. The size and connector are usually different. A regular front blade may not fit or work correctly.
My Rear Wiper Stopped Working. What Should I Check First?
Start by checking the fuse and listening for the motor. If the fuse is good and the motor makes noise, check for jams or a broken wiper arm. If nothing moves or you hear nothing, it may be an electrical problem.
How Do I Refill The Rear Washer Fluid?
The washer fluid reservoir for both front and rear is usually under the hood. Open the cap, pour in fluid until full, and close tightly. Use a winter-safe fluid if you live in a cold area.
Is The Rear Wiper Covered By My Jeep Warranty?
If your Grand Cherokee is still under the basic warranty, most electrical and mechanical parts, including the rear wiper motor, are covered. Blades are usually not covered, as they are considered wear items. Check your warranty booklet for details.
Keeping your Jeep Grand Cherokee rear window wiper in good condition is easy and protects your safety on the road. A few minutes of care each season can prevent bigger problems and make every drive safer. Remember, the rear wiper is a small part—but it makes a big difference.
