I have replace everything, included windshield, wiper rubber blades... but it still skipping while running. why??

Get some rain Coating. Apply in the wiper as well

Angle salah maybe?

see if the wiper is sitting properly.. the wiper arm may need some minor correction if it doesnt

New wiper most likely to skip because the rubber has some coating to protect it while waiting to be sold.

I guess after a while it will go smooth. You can just buy Rain-X or anything similar to it and applied to the windshield. It will become smooth.

i did to my old windsheild, it only good for few days, no use for long term, it came back..

tried, i adjusted 90 degree to the windsheild surface, but still skipped.

it skips, not matter new or old wiper, initially i thot it was some stubborn dirts on my old windsheild, but after replacing it, the problem persisted...thats really confuse me...

tried already, it skipped no matter what angle i bent..

for your information, i also replace the wiper linkage too, but unfortunately, the problem persisted..

Have u tried tighten the arm?
Happened to me before, ends up the arm longgar.

i checked that after i replacing the wiper linkage, but still skips..

since it skips, might as well go for silicone

How old is your car, happened one mine and i had replaced the wiper.

The problem went away aftr that.
Over time, the spring in the wiper arm looses tension and it doesnt 'press' the wiper balde against the glass effectively.

If yours is an older car, you could consider it.

What wiper do you use? Often is because the wiper material not good also.

Reputable wiper or not

try to polish ur windscreen first..

buy new car

which brand of new wiper you are using? I am using cheap silicone and it is skipping after a few time using. It's fine since it is cheap. I rather not spend 10x the price to get PIAA. It only skip when windscreen not wet enough. Heavy rain, it's fine.

Assuming if you already replaced the windshield, if you are driving an older car can be arm or linkage. If arm is bent usually it will skip only on one direction but not the other. I see that u replaced linkage as well, then the only thing left will be try to lift up and down the wipers to check whether the hinges of the wiper arms is providing enough pressure and is there any slack. If got, then that is the issue. What vehicle is this btw?

Put dishwasher in your windscreen water reservoir

funny thing about this solution
my wiper previously also skip

i got free bottle of windscreen washer, instead of pouring it into the water reservoir
i put it into a bottle, mix it with water and spray it all over the windscreen and wipe it
it did resolve the issue

but i'm not using cheapo wiper, am using bosch aerotwin

Bosch aerotwin skips like mad 😭 adjusted angle to be perpendicular with the windscreen at both the starting position and maintenance position with 2 spanar method, arm tension got.

I noticed when it stops at maintenance position the spread of the wiper is not consistent though. Some facing forward some backwards.

Windscreen is clean too just done coating. The same aerotwin put on another car, wipes perfectly streak free

Have you resolved your skipping? Bothers me crazily since its brand new and skipping

coating is keyword. d shop done something to ur glass

Need to clean the blade w tissue as well.
Personally I think NWB makes better rubber wipers.

Possibly, because it was all good with old wiper until maintenance wash ("refresh" coating done a year ago) + wiper change recently

Right, the shop was kind enough to help check on the problem tomorrow. First time hearing NWB tho, Jap co? If the problm is not solved I'll try out NWB then. Rubber wiper all the way instead of silicone

NWB was the OEM supplier for Myvi 2006 wiper last time. I used a few pairs already.
Nowadays seem to be under Denso umbrella

The con then: Not commonly found at all spareparts.. unlike bosch.. but nowadays with shopee and all easier to buy online

Shop redid the coating ... Seems like the shop had to thin out the coating to balance between the skipping. Water doesn't form beading as much now. But the wiper performance did improve. Citing "new wiper was very soft and melekat"

Thanks for suggesting NWB, will definitely try it out next pair. Cheaper than aerotwin too

Is it like rainx coating? Where rain water becomes droplets and easily flows away?

Rainx is silicone based, then you have Aquapel, Soft99 Glaco, etc etc. I did ceramic coating for my windscreen. Yes water beads instead of sheeting

Is there any advantage of trying to lift up the wiper and put it down so the blades touch the screen straight 90 degree rather than slanted after usage? because when the wiper sweeps and returned to the park position it (the blades) will usually be slanted at an angle due to direction of the sweep.

all else fail, just try change the wiper, i suggest NWB aqua, previously other brand i tried all chatter, but NWB is the least sound and chatter of all. NWB aqua is cheaper than aerotwin or PIAA also.

the wiper arm spring is too weak to hold the wiper down now with the coating and all
plain glass and silicone doesn't judder, but with additional coating it will 'grip, let go, grip, let go' and cause judder
