On most modern Grand Cherokees, the rear wiper blade is 13 inches. Older generations use larger blades, typically in the 15–16 inch range. Always confirm for your exact year and trim by measuring the current blade or consulting the owner's manual or parts catalog.
Understanding blade sizes by generation
The Grand Cherokee has spanned multiple generations, with blade sizes that reflect changes in rear window design. Below is a practical guide to help you start shopping, followed by ways to confirm the precise size for your SUV.
- Modern Grand Cherokees (WK2 and newer, roughly 2011 onward): rear wiper blade is 13 inches.
- Older generations (pre-WK2, including the ZJ/WJ/WK line from the 1990s–2000s): blade lengths commonly range from about 15 to 16 inches, depending on the exact year and body style.
Because there are many overlapping model years and occasional trim-specific differences, always verify the exact size using a measurement of your current blade or the official parts diagram for your vehicle.
How to verify the exact size for your Grand Cherokee
Use these steps to confirm the precise blade length if you cannot locate a catalog entry:
- Remove the current rear blade and measure its length along the edge, including any curved portion.
- Check the blade packaging for size markings or the part number, then cross-reference with Jeep's parts catalog or retailer listing for your model year.
- Consult the owner's manual or a dealership service department for the recommended blade size for your specific VIN/year.
With the correct size confirmed, you can ensure a proper fit and optimal performance in varying weather conditions.
What to buy and how to shop
After you confirm the size, shopping options include OEM-style blades and compatible aftermarket blades. Note that 13-inch rear blades are common for WK2-era Grand Cherokees, while older generations may require a larger blade (often 15–16 inches). Verify the mounting adapter and ensured compatibility with your hatch wiper arm.
Summary: The rear wiper blade size for Jeep Grand Cherokee depends on generation. Modern WK2-era models typically use 13 inches, while older generations commonly call for 15–16 inches. Always confirm by measuring or checking official parts diagrams to ensure a precise fit.
