Wiper blades noise!!!
 
The wiper blades noise is driving me nuts. I replaced the wiper blades with a new set of Bosch blades. Now the noise is more, when the wipers come up they vibrate/rub to the windshield and make irritating noise, while they are fine while going down. This noise changes accroding to the speed at which I am going and also the direction of the outside wind. Is there any way I can get rid of this noise (except getting rid of wipers :p )?? I can't stand this noise any more, the wind noise that I get from front doors and sunroof is enough to drive me nuts.

try some rainx it might act as a window lubricant

Your problem is that the angle of the blade to the windshield is not quite right.

With older blades, this happens all the time because the blades have sat too long at an angle to the windshield at rest in the hot sun. They take a set and because the windshield is slippery from the rain, the blade won't flip back and forth but just lays on one side as it goes back and forth across the windshield, sometimes rattling as it goes in the one direction, not quite flipping. Making the windshield even more slippery will let it stay on one side more likely, but will probably reduce the noise. Not the perfect solution. I sometimes reverse the parked blade leaning to the other direction when the car is parked in the sun, just to reduce this set problem.

Regardless of whether this happens with old or new blades, you sometimes have to give the arm a slight torsional twist to change the angle of the blade just a little. That way the blade will be set just right to flip back and forth as it should. It takes just a little experimentation to get it right.

Patience and trial and error twisting should do it. I have done it many times to various Alfas.

Good luck

Is the wiper arm hitting the under side of your hood? It's common.

I will try RainX today and see howit works.

How about Trico Innovision wiper blades, anyone had any experiences with those blades?? NAPA part# WIP602142

If your blades are rattling because they are not flipping as they should, I found that changing blade brands doesn't help, as it's a arm geometry problem as stated before. I have had to do this many times on Alfas. Other cars may be the same.

Listen to Del, seriously. Don't do the RainX thing. You will either have to keep applying it religiously or you will have to wait til it wears off to get ANY wiper to work correctly (and be even more miserable in the meantime).

I would say that the blades are at the wrong angle. I would also say that the Bosch blades are junk! If you can find them get a set of Nippon blades. They are labeled NWB. They rock! I have been fooling with a wiper issue on my 06 Grand Vitara. The blades that came on it new were a little streaky ( probably from sitting ) so I threw a set of Bosch blades on. They were ok for about three days and then they started streaking. I then noticed that they were lifting at speed and chattering like hell at speed. Switched to the "new" frameless Bosch blades. I also put a set of the same blades on the 164 the same day. These are even worse than the normal blades. At 25.00 a set they really pissed my off. Changed to the Nippon blades on both cars and they have been perfect for three months now.

I have always used just the basic Bosch inserts which I install into the old blade holders attached to the arms. They have worked fine for years, I have no complaints. I think it is a waste to buy all new holders as well as the blades. It is getting harder, though, to buy just the blades. Companies make more money on the entire setup.

I bought Bosch wiper blades.....once. Short lived. THE worst product Bosch makes. I normally pick up Anco or Trico, seem to be the best that you can find at the typical A/P store. I buy the whole blade now that they seem to be reasonably priced these days AND they work best AND hassle free, slap 'em on in under 2 flat.

When I sold spark plugs at the parts counter ;) we would get tons of people who bought inserts/blades and the like. Many could not install them or they bought the wrong size so we would replace or refund the purchase. Now the packaging was ripped open so they were almost impossible to sell so the employees would get to take them home. I have or had dozens of blades and inserts and full wiper arms too and the Bosch were way overated and overpriced. Trico was fine and Anco is good too and much more reasonable.

As far as the chattering goes, my wiper motor was defective and would do this and also not stop on the bottom of it's arc. I recently replaced the motor and no more chatter.

Del is right, the arm needs a slight amount of torque or twist applied to it so the blades lay at the correct angle to the windshield. I had the same problem and changing to a different blade didn't help. You just have to experiment with applying a little force. Although someone told me the "spring" action of the arm itself might wear out on a ten year old car, couldn't confirm that though:) .

What direction should the "twist" be in? Down towards the bottom of windshield or up towards the top?

spaten136 02-27-2007 06:16 PM

you can see if the wiper is making the correct motion by hand. the rubber part should "flip" as the wiper switches driections, so take a good look and twist it in the direction that would make sence. then try it, and go from there

Del 02-27-2007 06:57 PM

It does take a little experimentation. Usually you can look at the rest position and tilt of the blade, and make the twist a little in the opposite direction. As long as you don't overpower the arm, you can experiment to your heart's delight. You can also look at the blade as it swipes to see which side it is laying on all the time and twist appropriately.
