Just replaced passenger side front wiper blade as previous one was juddering (not bad for 2 yrs old). Fitted genuine Honda, as always from Cox Motor Spares, and judder gone and wipe is great. Decided to change Drivers side as of the same age. Again fitted brand new genuine Honda blade. Blade misses large patch with top tip of blade and a patch in the middle of the blade. Never had problems with Honda blades. Swapped back to used blade and wipe is perfect. Any idea why new blade is missing on wipe, any suggestion on how to fix or could it be a faulty blade. It appears to be same curve etc as old blade and everything looks ok. Will carry on with old blade for now.
