To find the correct size, check your owner's manual. It will list the proper wiper blade sizes for your specific Cavalier.
Alternatively, you can:
* Look at the current wipers: The size is usually printed on the wiper arm itself or on the wiper blade.
* Use an online tool: Several websites allow you to enter your vehicle's year, make, and model to find the correct wiper sizes. Be sure to double-check the results.
* Go to an auto parts store: The staff at an auto parts store can look up the correct sizes based on your vehicle's information.
Avoid relying solely on generalized information online as the sizes can vary slightly between trim levels. Checking your owner's manual is the most reliable method.
