Windshield wiper streak

On the drivers side just below straight on I get an area that doesn't wipe thoroughly. It happened with the OEM Trico type blade and I replaced it immediately with a Goodyear beam type that I buy at Costco for $7. That worked better but not perfect but when I replaced it with a second Goodyear it's really bad now.

When the wiper is 1/2 through it's cycle the wipe is perfect put when the blade returns it's bad. It's about 3" wide and 2/3 of the swept length.

Does anyone else have this problem? I'd like to know what brands work better. I like the beam type because they don't freeze up as easily.

Re: Windshield wiper streak

I have the same exact problem and its driving me nuts... I just replaced mine with rainx latitude blades which are much much better than the factory ones but I'm still getting a little bit of a water streak when they come back down.

Does anyone know if the spring on the wiper arm can be adjusted to add more pressure on the windshield???

Re: Windshield wiper streak

Probably you all need to really clean the windshields. I'm not sure if you can do it on the rain sensing windshields, but on a normal windshield some 0000 steel wool should do the trick.

Re: Windshield wiper streak

I switched over to some rainx wipers and they have been great. The stock blades were terrible.

Re: Windshield wiper streak

The windshield is as clean on the driver's side as it is on the passengers, and the issue is only on the driver's side, so I don't see how cleaning would make a difference. I keep it clean with windex like any other vehicle I've owned and this is the first time I've had a problem.

There is no way to adjust the spring pressure unless I modify the spring or replace it with a different one. The same spring is used on the passenger side, again no problem with that.

I do notice that there is a different bend in the wiper arm between both sides that sets the starting angle (between the blade and the glass); however the starting angle appears to be the same on each side. The angle is such that the blade is "pulled" in the up cycle and "pushed" in the return. As I said earlier the blade wipes clean on the up (while being pulled) but not on the return (when being pushed). I'm thinking that this might be causing the issue.

Re: Windshield wiper streak

My OEM wipers work fine - no streaking. And when they need to be replaced, I will spend the few extra $'s on Mopar replacements.

I have always gotten best results/quality and 2-3 years service out of OEM wipers. Most aftermarket replacements only last a year or so, in my experience - even the more pricey Bosch, etc.

All wipers need a cleaning with a cotton-ball soaked in alcohol solution (I use 70% rubbing alcohol) once in a while to renew the edge. I usually do every spring and fall with the season changes.

IMHO.

I watched mine today on the up stroke they make contact the entire path on the down stroke it lifts off the windshield.

I've cleaned mine (has rain sense) with 0000 steel wool with no problems.

Per what hacksaw mentioned, I had this same issue as well. Tried tweaking the bow in the arm a bit to add some extra downward pressure on the glass. No dice.

As for the streaking, I've had several sets of blades that did this. Tried adjusting the driver's side wiper arm at the mounting post a bit to give it a lil extra range during the outbound swipe. Seems to kick that extra lil bit of pooling off the windshield to help eliminate the streak of death. On another note, I've been using RainX Latitudes with zero problems ever since I moved the arm a bit.
