Problems with windshield and wipers

[Sayantsi]

Thanks...I didn't know there was an adjustment. I took it back to the glass guys and in 5 minutes they restored the wiper travel back to perfection.

Glad it worked out! I've had the same problem before when having a windshield replaced and it drove me crazy until i fixed it.

For new blades I found the Michelin brand at the Canadian Costco at half the price of any where else. On-line they carry Good Year also at half the price. http://www.costco.ca/Browse/Product...Ntt=WIPER&No=0&Nty=1&Ntx=mode matchallpartial

Midnight,

Great find...thanks for sharing!
I hope they fit on the Genesis.

I also had the clicking and the local dealer also used the "normal operaton" line. I used two coats of RainX on the entire windshield and there is no more click.

I guess mine is more of a "clack" at the top of the stroke of the driver's side wiper. I've checked and there is no contact with the frame. It appears that when the wiper blade changes direction of travel at the top of the stroke, the rubber blade "lays over" on it's other side making a pretty noisy "clack" or "thwap" when it does. I had a similar problem (but not as noisy ) on my '98 Volvo S70. Like dond13 states, RainX seems to remedy the noise (until it the coating wears out).

You are right about it returning. I re-applied the RainX at only the top left of the windshield and it was quiet again. I will buy a new set of wiper blades and see if they hold up longer.

I have had issues with the windshield on my Genesis. I was certain that it was caused by me, but now believe it is a defect.

Had the car for about 2 months and started noticing the top left area make a thwap sound when the windshield went up. I thought it was hitting the edge, but relized it wasn't. In fact if you put your finger where it makes the sound it will pretty much go away (don't recommend that). I had the dealership replace wipers and still had the issue.
I used rain-x on it and had the same issue- it actually made it worse for me.
Then, about week later got a rock and had the windshield replaced with a nice new windshield. I was certain that it would fix it, but still had the issue. I worked with them to adjust the arms on the wiper.
Took it back to the dealer after a while and the service tech showed me on the actual windshield where you can feel a small indention in the glass and they believe that is causing it.
So, the ordered another windshield. Before they put it in last week we checked the windshield and it had the exact same issue on the windshield they were going to use. They said it is OEM and set to Hyundai.
So, now the dealership is going to try another windshield to see if they can find one without the indention that is causing the thwap sound.
Windshield company recommended non-OEM blades.

Thought I would share in case someone else is going crazy when it rains.

I replaced mine with some Rain-X Premium blades and they are 110% better then the stock ones...zero streak issues and they provide a quieter wipe in the process. Also I would suggest getting rid of the junk washer fluid in the system a.s.a.p. and using the Rain-X branded fluid with bug remover...it keeps the windows nice and clean and powers through love bugs etc...

Check to make sure that the film your seeing is not on the inside of your glass... it can get a build up over time especially if you or someone else smokes inside the car.

Best Wishes.........Bruce.

New windshield--now the auto wipers don't work as well

Windshield took a rock and was replaced. Now the automatic wipers don't track the rain intensity well anymore. They do work, but hard rain brings a too-slow sweep. Are there adjustments? Should I go back to the windshield installer or the dealer?

I am sure glad I found this thread... I have aftermarket blades...I can't remember the brand, but they were a more expensive model from Advance Auto Parts... The first set made a noise on the driverside side just like everyone has mentioned. I took the blades back thinking there was a problem...the noise went away temporarily..and then the sound came back at the end of the upstroke on the driver side.

Today, I went to my dealer to buy OEM blades thinking the blades are to blame. They didn't have them in stock.... I guess I will look into applying rainX to my windshield in hopes of the noise going away. I was in a storm today for about an hour that nearly drove me insane with the noise.

Thanks

I started hearing a thumping sound with the wiper on the driver side last Wednesday. Last Friday brought the car into the dealer and they ordered OEM blades. Told me they will be in on Wednesday with the usual shipment they receive. Also told me to stop by anytime on Thursday and he'll replace them at no cost (1150 miles on car). I went by today at 2:30 pm and both of the wipers were replaced with OEM blades (arm did not have to be replaced). Service rep told me should replace both blades at the same time. The thumping sound is gone. Asked me if I wanted a car wash but told them I do it myself. Left at 3:00 pm.

I'd like to hear how they sound in a month or so.... I've got a wicked thump sound when its raining... kind of annoying if you're traveling for a long period of time.

IMHO it's a design flaw. I get the "thump", "thwack", "clack", or however it sounds to you at the top of the wiper stroke when the blade changes direction. The blade does not make contact with anything but glass, so it's not the sound of hitting the A-piller.

The blade, which lays on the glass at an angle on the up-stroke, must rise up and lay down again on the other side of the blade when it changes direction at the top of the stroke.

I've noted that the blade has a lot of lateral play in the bracket where it mounts to the wiper arm which allows the whole wiper blade assembly to rotate perhaps 5 degrees either side of perpendicular with the glass surface. Since the blade has a curve to it, when the blade twists laterally, the tips of the blade end up "trailing" the center of the blade as the blade stokes across the glass. When the blade reverses direction, that curve has to shift in the other direction which results in a lot of movement of the blade pivot point and a significant amount of noise.

You can kind of duplicate the situation by putting your wipers in the "change blade" mode (Turn your car on, then turn it off. As soon as you turn it off, push the wiper stalk to the "mist" position and hold it. The wipers will go up and "park" at the top of the stroke). With the wiper blades in the "parked" position, you can manipulate the wiper arm back and forth a few degrees and recreate the noise when the blade reverses direction and lays down on the other side of the blade (I do this by moving the passerger side arm so that I'm not even touching the driver side arm...which appears to make the most noise). The noise is not as loud as when I'm driving and using the wipers, but I can't make them move as fast (nor do I want to) and I'm certain that the airflow over the windshield at driving speeds has a part to play in the issue.

If you rotate the wiper arm up away from the glass (like you were going to change the blade) you'll note that the pivot point has A LOT of lateral play in it (just grab it and wiggle it back and forth). I checked my wife's car, which has the more conventional 8-point wiper bracket, and its very tight laterally. It does not rotate, thus the blade tips are tracking in the same axis as the center of the blade. I'm trying to figure out if I can stick some shims in the wiper bracket on the Genny to tighten it up and see if the noise goes away.

In reply to mcginnpm's post....

I switched over to the Rain-X Latitude wiper blades and they made all the difference in the world. They are totally quiet and provide a superior wipe in comparison to the OEM blades. They move a higher volume of water/snow etc.. off the windshield with every pass and hold up well against the elements (hot/cold and resist cracking of the rubber and such). I have also heard that the Michelin Pylon wipers are excellent..but very pricey ($25+ per blade)...in my opinion well worth the $$ ..u can't put a price on safety.

Never had a problem with the OEM original blades (see below) and no problems with the replacement OEM blades purchased at Hyundai.

OK, now you want to know why I replaced my original blades if I didn't have any problems with them. Its because when I went out to Roswell last December, lots of cold and ice (and snow on the ground), one morning I started out at a temperature of 11F, put my wipers on to clear the windshield, and the ice broke a piece off of my driver side blade. I carry an extra set a blades with me, so I changed them, and when I returned to Florida, I purchased new ones at Orlando Hyundai, and keep them for the next emergency.

gameday22 & ctrcbob,

Could you do me a favor and check your wipers blades to see if they have a lot of lateral "slop" in them (i.e., when you twist the wiper blade around the blade axis) and let me know if yours appear to be loose or pretty tight.

I've attached a PDF with pics of my driver's side blade. I've twisted the blade full left and full right in each picture. I held a paint stick flat against the wiper blade housing to highlight the amount of "slop" I've got. I'd estimate that 80-90% of the "slop" comes from the mount in the wiper arm whereas the other 10-20% is "slop" in the integral pivot point of the wiper blade.

I'm still thinking most of the noise folks are hearing in the driver's side wiper blade at the top of the stroke is from this "slop" (kind of like the old days when you didn't adjust your valve lifters properly, and they made an aweful racket due to the "slop" in them).

It's been a month since I had the wiper blades replaced with new OEM blades. Been through few downpours. They are still nice and quiet. It's great not to hear that thumping noise. The technician recommended double wiper blades for those still with thumping noise problems.

Nope...you're not. I'm online at 5 AM too frequently, usually because I haven't been to bed yet (my days off work) if I'm on at that time of the morning.

I don't notice this, it's pretty tight and not giving much play from side to side with each wipe..which of course would add a lot of noise to each move of the wipers across the windshield. I got rid of the OEM's right away and have been very happy with my current blades. They provide a superior wipe and are a lot quieter while doing it. (Michelin Radius) and they now have a newer blade called the Michelin Symphony ..both guarantee a streak free wipe and greatly reduced noise.

Hope this helps some

I just thought I would update you on my situation.

It was actually the windshield that caused the issue. The 3rd one they put on it did the trick with OEM wipers.

You can put your finger right where the sound occurs and feel a slight indention in the glass. Each glass company blamed it on the Hyundai windshield specs.

The dealership finally found a non-OEM windshield that worked without the noise.
