Hi guys,

I started a thread about this long ago, somehow I could not find it anymore.

My Alterra's wiper problem is back. Well it was never gone really. Now that it is raining again, we have to use it and thus have to deal with the problem again.

I have buffed my windshield about 10x now, I have applied all the fluids (mwatermark remover, Rain X). These are temporary solutions as after a while of constantly running the wipers (especially at higher speed), I am getting that juddering sound again. I have also already changed wiper blades.

Last time I went to Isuzu, they couldn't do anything about it and their only advise was for me to apply a shampoo - they recommeded rejoice at that Did this and as expected, was one of the temporary solutions.

In contrast, my Vios' wipers are smooth as a cue ball. I never applied anything on it.

I am willing to pay a lot just to have this fixed permanently.

Any help will be greatly appreciated.

Thanks
