Sizes vary by model year and trim. For most modern Grand Cherokees, the front wiper blades measure 26 inches on the driver’s side and 20 inches on the passenger side, with the rear blade around 11 inches.
Why blade sizes vary by generation
Over the years Jeep has updated the Grand Cherokee’s design, which can affect wiper arm length and blade lengths. Different generations or body styles may use different front blade pairings, and the rear blade is typically smaller. To avoid guessing, always verify for your exact vehicle by checking the owner’s manual, the windshield wiper panel on the car, or a parts retailer’s compatibility tool.
How to confirm the exact size for your vehicle
The following steps help you determine the correct wiper blade sizes for any Grand Cherokee year and trim.
- Inspect the current blades: look for length markings on the blade itself, or note the length printed on the packaging if you’re replacing them individually.
- Measure the blade lengths with a tape measure when the blades are removed or laid flat, to confirm the exact inches.
- Use an online parts catalog or visit an auto parts retailer with your vehicle’s year, make, model, and trim to verify compatibility and order the precise sizes.
Before ordering blades, consult the owner’s manual or the vehicle’s maintenance section for the recommended sizes.
By confirming through these sources you ensure you buy the correct sizes, avoiding fitting issues or poor wiping performance.
