XC60 2019 heated wiper blades problem

[comtec5]

hi my heater front wiper blades after 3 months are now making a squeaking noise and also juddering. they are quiet when its raining heavy.

I would like some advice, if this is normal and if not on how to solve the problem.

I have only owned the car for 4 months and the original wipers did not clear the windscreen so i replaced them 3 months ago.

Hard to say to be honest.
What I would do with mine is clean the windscreen perfectly, polish it a bit then put a ceramic coat on.
Clean wipers and touch them with a ceramic coat.
I did it 2 years ago and no problem with wipers till now as my windscreen was replaced recently, I am starting to see what you having.
Next week ceramic coating will be applied on.

At least last time it was working for me.
