Windshield Wiper Chatter

I cant seem to understand what causes my wipers to chatter along the glass.

I have thought of these reasons

1. Poor Quality Wipers (oem)
2. Worn Wipers
3. Winshield too dry

Of these three reasons i can think of they dont seem to be the prob besides #1.

Does anyone else experience this with the oem wipers.

Its weird because when i first got my car you couldnt even use them, so i immediatly replaced them.

However i still experienced slight chatter with brand new oem wipers, and they will chatter regardless of how hard it is raining some times more or less when heavy rain or slight rain, its not consistent.

your three guesses sound the most logical - I occassionally apply RainX to improve the wicking and wiper performance...

The OEM 6er wipers are great. I get no chatter even if I run them on a dry windshield.

I would first try cleaning the windshield with a good cleaner and a microfiber towel or newspaper.

I would also grab some wiper rubber treatment. I use 303 Wiper Treatment Wipes.

If that does not work then I'd go for some glass polish. I've used SONAX Glass polish to get rid of water spots and it worked great but there are lots of other brands out there. Don't go crazy with the polish if you are using to clean.

Had the windshield chatter too, went away after I replaced the wiper arm spring as the spring pressure was not up to par.

That is another thing i thought of but forgot to mention.

You mean the wiper is pushing down too hard against the glass, correct?

He means not hard enough. You probably have to buy a complete arm, I don't think they sell the spring on its own. Left arm is ~$50 right arm costs ~$100.

BINGO!

piss's me off that they dont make the icons for the e39..

Im on a mission to cut and weld new ends on my wiper arms ill post up when i get around to it..

I have been having this problem lately too. I was wondering if I should replace the blades with blades from Autozone/pepboys or order oem ones from bavauto.com. Anyone have any suggestions on what brand to buy.

It may not be the blades, it happened to me with brand new oem ones from the dealer

Please post the fix, I am hoping you find a universal solution as my wife is also prone to excessive chatter!

Oh and ill also add that you don't have to cut the refills... just put em on as you get em...


lol opps... thats for the e39'ers not you lot

Wiper chatter is almost always a result of worn out rubber or a dirty windshield.

Step 1 is to thoroughly clean the windshield. Use crumpled up black&white newspaper and your favorite cleaner first. (i.e. Stoners Invisible Glass) If that does not work try using a claybar to remove built up crud. If that does not work go for a glass polish used sparingly with light pressure, it will cut through anything.

If cleaning does not work Step 2 is treating the rubber wiper blades. Use something specifically made for wiper blades like 303 Wiper Treatment. This also prolongs the life of your $40 - $100 refills.

Step 3 is replacing the wiper blades. My OEM blades do not chatter at all.

If you want to go nuts you can also use high-end windshield wiper fluid that you mix yourself from concentrate instead of using cheap $2 fluid which is hard on your rubber. Your blades will last twice as long if you use this stuff. A few of my friends use P21S Windshield Wash Booster and swear by it. BMW sells something similar which I think is rebranded P21S.
