winshield wiper does not scoop in the middle

ReverseHandedJO 10,459 1,770 October 22, 2015 at 05:34 PM
okay so i have this odd situation where the driver side windshield wiper does not scoop in the middle, just on both ends of the wiper. so vision an unscooped circle about the diameter of a basket ball right in the middle of the driver side windshield where you need to see out. i have switched the wiper arm/blades twice now, so the original is back on the left. the only other thing i can think of is to bend the arm from the motor that connects to the wiper arm so the it is applying a bit more pressure to the middle. the arm/wiper (both) worked on the right side. i did notice that when the right side arm from the motor without the arm/wiper is down to the windshield there is about a 1/4 inch gap, but i did not check the driver side gap without the arm/wiper.

Look carefully the the book for wiper blades at the store, sometimes they recommend a different size +/- 1" in certain brands/models of wiper blade. Try one of the newer style blades that flexes like a spring.

You might be able to buy a rubber insert for the stock blades. The motor doesn't apply pressure to the glass, there's a spring in the arm that does that.

BIL just went thru this on a 93 Jag. Thought the windshield was warped in that area and Insurance covered replacing the windshield. That did nothing. It turns out that the wiper motor was misaligned somehow and had to be re-positioned. Now that car only has 1 big wiper so it may be different.

Are you using the new single bar type of wipers or the old style with a lot of metal pieces? Some cars do not suit well with the new style and have issues like you explain.

What year and Make and model of car? Just because this thread doesn't involve a computer doesn't mean details are not unimportant.

I am assuming your using after market wipers that are not new?

I would replace the wipers, not just switch them, There are a couple of styles, some manufactures like Honda allow you to just replace the rubber insert on their oem blades as this is what wears first. You can replace the metal frames too and that might be what you need to do. It's possible the internal wiper transmission has problems but i doubt them lifting would be a symptom. Most wipers pivot out to help clear ice and snow, you might make sure no hoses etc are caught in the way while they are down. I could see that happening easily.

If the wiper is making good contact then we can approach cleaning methods but I doubt this is it.

so i did some googling and it appears that this is a common problem people are experiencing with replacement oem wiper arm/blades. seems the fix is to slightly bend the driver arm from the motor towards the windshield 2-3 degrees. i havent done this yet, but i have talked with a couple of people that did this and it fixed the 'skip' problem.

Iagree

Buy entire blades, not just the rubber portion that contacts the windshield. Something like http://www.amazon.com/Rain-X-5079...iper+blade . Make sure to get the correct size for your vehicle, and note that the passenger and driver side blades are likely different sizes.
