How do I know if my wipers need to be replaced?
If your wipers clean your windscreen unevenly, it is a good sign that your blades have deteriorated. If the wiper fails to make proper contact with the screen surface, you’ll get streaky or unwiped areas which will impair your vision. Unusual noise or chattering is also a clear warning sign.
A) Lines
Wiper rubber can harden or become damaged with age. The result: fine semi circular lines of water on the windscreen.
B) Bands
Wiper rubber can harden or become damaged with age. The result: thick bands of water are left on the windscreen.
C) Lace Curtains
Arm defects or long periods in the park position can deform the wiper blade lipcausing a veil effect across the windscreen. Visibility danger is greatest at night, when passing other vehicles.
D) Chatter Hopping
Deformed wiper element, worn blade linkage or a change in wiper arm characteristics can cause wiper blades to judder across the screen leaving behind radial streaks.
E) Unwashed Margins
Deterioration of wiper blade linkage or decreased wiper pressure can leave parts of the windscreen unwashed.
F) Noise
Noisy wipers may be sign that the wiper element is deformed or hardened or that the wiper blade structure is worn.
G) Vibration Judder
Deformed wiper element, the wrong adaptor or aging and wear of the blade rubber and links can result in jerky and sometimes noisy wiper arm movement.
H) Wind Lift
If high speeds persistently cause the wiper to miss out parts of the windscreen, either the wiper blade or the wiper arm should be replaced.
