How to Buy Wiper Blades


What the best windshield wipers have

  • Outstanding performance when new. Expert tests find plenty of wiper blades -- including some cheap ones -- that do a stellar job cleaning the windshield, so there's no reason to settle for anything less than perfection at the outset.
  • Good performance for at least six months. Anecdotal reports from owners suggest that some brands last longer, but professional tests show that most wiper blades (regardless of price) wear out after six months.
  • Connectors to fit your vehicle. Hook-style connectors are the most common, but some vehicles use pins, pinch-tabs or bayonet mounts; most windshield wipers come with adapters for all of these, but double-check before buying.

Know before you go

What size do you need? Some vehicles use different-size wipers for the driver and passenger sides. Auto-parts stores can look up your wiper blade size for you, or you can check your owner's manual. If you're buying online from a site like, it's a good idea to double-check the size; we found plenty of complaints from frustrated owners who say's wiper blade size finder wasn't accurate.

What type of wiper blades came with your car? Many new cars come with newer beam-style wiper blades as original equipment. You may need to replace these with another beam blade; a bulkier, traditional bracket-style wiper blade might not fit.

Which connectors do you have? Most new cars use easy, hook-style wiper blade connectors. Replacing this type of wiper blade is a pretty simple do-it-yourself job; has a great step-by-step tutorial with photos on how to replace your wiper blades. However, the article admits that not all windshield wipers are this easy to replace. "A variety of arms and mounts have been used over the years," author Joe Bruzek explains. "The stubborn ones with pins and unique latches can churn up rage so deep that the new wipers may turn into boomerangs before they're ever installed." The good news? Some auto-parts stores will install your wiper blades for free if you buy them there (For example, Advance Auto Parts and Pep Boys both advertise this service).

Do you need silicone protection? Most wiper blades are made of rubber, and this old standby still works great; in one leading wiper blade test, all of the top performers are standard rubber blades. However, pricey silicone wiper blades are favored by off-roaders, who say they shrug off heavy mud and dirt. Also, many owners — particularly those who live in climates with scorching summers — praise the silicone blades' superior durability. So if your car has to deal with extreme conditions, either on or off the road, silicone wiper blades might be worth the high cost.

Value expectations: The dollars and cents of it

At first blush, it might look like it's a better value to buy just the rubber inserts for your windshield wiper blades, rather than replacing the whole blade assembly. However, buying the inserts is only slightly cheaper, and experts say installing them can be a pain. The windshield wiper buying guide at says that replacing the rubber inserts requires "deft use of needle-nose pliers," while the new blade assemblies simply snap into place. Besides, once your blades are shot, the frames probably are too, Popular Mechanics points out. So both sources recommend just replacing the whole windshield wiper —both of them. "If one is worn out, its mate can't be far behind," says. "Don't forget to check the rear wiper, if your vehicle has one."

Also, don't expect your new windshield wipers to come with a warranty. The only wipers we've seen that came with one were high-end silicone wipers, like the PIAA Si-Tech (Est. $30). A warranty on a standard rubber wiper wouldn't help you much anyway, since professional tests show that even good wipers — no matter what the price — don't typically perform well after six months of use.
