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?
