Wiper blade connector types: which one does my car have?
The common types
- Hook (J-hook or U-hook): the arm ends in a curved hook that the blade's adapter clips into. The most common type, and most universal blades include an adapter for it.
- Push button: a flat arm end that slides in and locks with a click; you press a square button to release it.
- Side pin: a pin on the side of the arm goes through a hole in the blade's mount. Pin diameters differ, so check the size.
- Pinch tab: two tabs on the blade's mount, squeezed together to release it.
- Top lock and bayonet: a flat arm end that slides into the blade and locks under a cap or clip. Names vary between brands, so compare photos rather than labels.
Why it matters
A blade of the right length with the wrong connector will not clip on, or will sit loose and judder. Universal blades come with a set of adapters, but not every set covers every arm, and a loose adapter is a common cause of noise.
How to identify yours
- Lift the arm away from the glass.
- Look at the very end of the metal arm and compare it with the types above.
- If you are unsure, look up your car on a retailer's fit list, which names the connector.
