Hi
Anyone else have noisy wipers on there C class?? And does anyone know how to fix it? Mines been back to the dealer once but still not fixed even though they told me they had! ! Driving me mad!!!

I had badly juddering wipers from new. The dealer installed new blades and it's been smooth since.

mine are doing the same, they fed me some BS about how you cant clean then cuz of a special micro coasting on them. They replaced em, the no longer chatter but now it a squeak where the chatter was. very annoying.

It's not BS. They have a graphite coating. Probably best to know what is right and wrong before you state it's BS.

Looks like I will have to get it booked in again. I was told the wiper arms were adjusted/lubricated but if anything they've made it worse.

so with the "graphite coating" im not supposed to clean off the wiper blades when i wash the car and there are normal to chatter and squeak across my windshield?

I have this problem.
I tried almost everything.. Vinegar, Sprayway glass cleaner, rubber lubricant WD40...
Dealer replaced wiper blades, wiper arms, adjusted different angles.

Please DO NOT USE RAINX!!!!!! It kind of started with RainX - I had the chatter issue and it was gone itself after several weeks, and it came back with more severe issue after I applied RainX.

Please post a solution if yours is fixed.

This is really annoying.

I took my car to dealership today, and they said they wiped the windows - got a tiny bit better but still annoying due to the chatters.

They opened a case with MBUSA, and there's nothing they can (or willing to) do at this time.

Damn, I shouldn't apply the freaking RainX!!!! Actually, the foreman in the shop suggested me to apply it...No luck with this product.

I had this for the first week or so and then it smoothed out. No issue now

Mine chatter. It's not as bad in HEAVY rain (like today's typhoon). I, too, would like to hear of a solution. I have to say, though, that they work very well -- visibility is great regardless of the weather.

Hoping it will go away after more use. Only 2018 km on the car so far.

If you applied rain-x to your window and need to remove it just clay the whole windshield and see if that helps.

I have this annoying noise problem with my wiper blade(s)..... which are genuine new parts I replaced old ones with.
Can anyone tell where this noise comes from? Or is it supposed to be like this? Surely not....
(just uploaded the video and it might take up to an hour for it to be converted)

Sounds like something is hitting a loose wire, or the wiper arm is catching on something... Wipers seem to be doing their job tho...

If I play music or radio, I don't notice the noise as much but that still annoys me. Time to take my car back to the dealer....
