The 2003 Chrysler Town & Country windshield wiper blade sizes aren't universally consistent across all trims and models. You'll need to check your owner's manual for the precise sizes. However, a very common size for this vehicle is
22" for the driver's side and 16" for the passenger side.
Crucially: Don't rely solely on this information. Always verify the sizes printed on your existing wiper blades or consult your owner's manual. Improperly sized blades won't effectively clear your windshield.
