To find the correct sizes, you should:
* Check your owner's manual: This is the most reliable source. The manual will specify the correct wiper blade sizes for your specific Cavalier model and year.
* Look at the existing wiper blades: The size is usually printed on the blade itself.
* Use an online auto parts store's website: Sites like AutoZone, Advance Auto Parts, or NAPA Auto Parts allow you to search by year, make, and model. Entering your Cavalier's details will show you the correct wiper blade sizes.
Don't rely solely on generic information found online as the sizes can change slightly across model years. Always confirm with one of the methods above.
