You're using the correct size right?

Driver Side -- 22 in (55cm)
Passenger Side -- 19 in (48 cm)

 

I had the same thing.i cut the angle more and filled it in. billet sells the shorter ones but big money. :drinking28:

 

Blade size didn't change only the angle the wiper sits on the post.

 

How did the cowl fit? I have one to do also. Did you drill holes in the cowl to install the push pin retainers in?

 

The fit is tight around the hood and it sticks up on the drivers side. The cowl came with Clpips for adjustments and screws that you bolt it down with. On mine I had to adjust were they went because there was no metal under where they wanted the holes drilled. The hood did have to be removed several times to ensure the cowl didn't move. The first time I put my hood back on the cowl had shifted to the passanger side.

 

Does anyone know if our wipers are with or with out splines? Found some for a suburbans rear window that will change the joint in the arm to what I need. Have a feeling it wont just bolt on though. With this arm will also be able to fill the nozzle holes because the nozzle is on the arm and not the cowl. Will get one from a yard this weekend for refference.

 

I do believe ours DO have splines

 

Might have to do a combination of the two wipers.

 

I could be wrong on that. Just going off my memory if it serves me correctly

 

I'll let you know later today as I'm removing my old rubber cowl today. So the wipers have to come off. Keep me posted if you find a solution to your wiper issue @Ace644

 

Maybe I'm missing something, but I don't understand how installing that wiper cowl would make your wiper arms longer.

 

<thinking> The new cowl doesn't allow the stock wipers to come fully to rest in the stock position, thus the wiper angle increased over the original cowl, thereby causing the wipers to wipe past the windshield</thinking>

Yeah, that should cover it, yes?

 

Nope. not buying that. This is as close to the edge as mine get no matter what angle. Looks like he's using a 24" blade.

 

It's the driver wiper at the top position. He had to re-clock the wiper because the cowl sits higher than the rubber one and has an angle recessed in it and that won't allow the wiper to be put on the same spot on the splines.

 

Other side...

Pull your wiper arms off, rotate them to his 'at rest' angle, and you'll see what he's talking about.
It sounds like A. They sent the wrong cowl, or B. Installed incorrectly.

 

Look closely at yours - the wipers, at rest, are in the black area of the windshield. Look at his, they are rotated higher up on the glass, so his driver's side wiper comes off the glass on that side.

 

Here is a better pic of the indentions on the cowl for the wipers. When I put them on as close as I can they sit about 2 inches higher on the window. Put the stock cowl back on and they are in the correct positions again. I've changed my blades several times since buying the truck. Always got the same size. I'm positive they were not switched with each other either because I took the driver off and put it in the driver seat and passenger in the passenger seat. It hardly ever rains and its so dry the blades don't last long here in AZ. Need new one almost every time it rains.

What about using a shorter wiper blade. Instead of 22/19 go with 20/17 and that may fix the problem. I looked at mine last night, still in the box. Didn't get to work on it yesterday something came up but when I looked at it I see what you are saying. Guess I'll have to deal with that too. Has anyone on here install one of there? If so what did they do? Maybe even give Street Scene a call and see if they have an answer.

 

The blades are not the issue. The problem is the angle of the arm itself. With the openings given with the new cowl they sit higher on the window not further out. When I turn them on to wipe my window being higher on the window the start and end point of the swing has changed. The entire driver side blade will leave the driver side of the windshield. The blade size never changed. They still fit the window fine. I will get better pics this weekend and mark my window so there is no more confusion.

 

Here are the pics that I hope will end the confusion of whether the blades are to long or not. The BLUE is the locations with the stock cowl. The GREEN Is the locations with the new SS cowl. As you can see the blades still fit the windshield just fine they do you over hang on the passenger side. If this were my problem I wouldn't have started the tread, I would have gotten new blades that fit. the passenger won't be a problem, but as you can see the driver side swings all the way the the middle of the A pillar. This is the problem I need to fix so I can use my new cowl.

In these pics you can see that with the new cowl I am unable to rotate the wipers any further with out taking paint off when I use them.

Please let me know if there are any questions or if you have a possible solution. Thanks

 

Unless you can find a different arm that will work, I really only see one other option and that's some surgery and fiberglass it back together.

Fiberglass is pretty easy to work with, but I know it may be intimidating if you haven't done it before. Advance carries repair mat and resin so you can get basically everything there.

 

Were the same ideas. Have done fiberglass before. Don't want to cut up the new cowl will save that idea if all else fails. Yesterday morning went walking around a few yards and got a few wiper arms from the rear window of the suburbans and trail blazers. the are almost the correct angle I need but not long enough. I'm thinking that to make it work my stock arm and one of the other arms will need to be cut and welded back together.

 

Ok, if you are absolutely sure of the positioning on the Street Scene cowl and it's locked down, here's a solution for you:

1. Install wiper arms into position relative to the new cowl.
2. Get a protractor and measure the degree difference from where the sheet steel ends and the upward bend begins, to a horizontal position relative to the new cowl. Write it down.
3. Make a quick and dirty jig by drawing a life-size picture of your current wiper - make an outline of the wiper arm if you need to. Place your protractor down and draw a line to the degree you wrote down earlier of where the wiper needs to be. I can eyeball it but I'm weird that way.
4. Carefully heat up the wiper arm at the bend you measured from and bend it to the position marked on your jig. Let it cool and check it to make sure you did it right and if satisfied, hit it with the can of flat black spray paint we all have rattling around close by to protect the metal.

5. Install the modified wiper arms into position and try it out. They will set a little higher on the glass than factory, but the modified angle of the wiper arm will allow a normal arc of operation without leaving the glass. Possible that you may need a 1" shorter wiper blade to keep them off the top edge of the windshield, but that's it. Paying for your art to do custom stuff, but I saw a Honda in the Walmart parking lot with that 'One extra big wiper' Ferraonda Euro mod sticking waaay up on the glass - if he can put up with that, you can live with this.

What do you think? Doable?


** I was so amused by your visual aids, I was motivated to do one of my own lol.

 

Sounds doable. Got tired of "the blades are to long" solutions that wasn't the problem. Probably easier that welding 2 arms together. Still going to try to use the sprayers though. Like the idea of spraying from the wiper and keeping the cowl clean. Will be easy to shave the nozzle holes. Also got some screen material to cover the holes with to keep debris out.

 

Bending the wiper arms to correct the arc (or sweep) of the wiper blade is the answer here, I've seen some on pricey vehicles that were almost a 'V' to get the sweep correct.
Also helluva lot cheaper to replace wiper arms than cut up that fiberglass. I'm still in shock over the stock replacement.
Up to you on the other stuff, personal preference there, this was a possible mechanical/engineering solution I thought up this morning. Plus I've had lots of wiper experience

 

Thanks for the help. Was exactly the answer I was looking for. I usually over complicate things. Will go to HomeDepo to get a torch when they open.

 

Probably a dumb suggestion but can u switch the motors around as far as angle swipe and where they come back to lay

 

OK, I understand the problem now. I wonder if there's a way to limit the sweep in the wiper transmission linkage.

Cutting the SS cowl so the arm is in the correct position might be the easiest solution.

 

Looks like the fiber glass wiper cowl needs to move towards the passenger side to clear the oem wiper travel.

I purchased the same SS wiper cowl and I'm planning on doing this mod soon. Thanks for posting this issue.

Right now the cowl is centered between the fenders and the wiper post are off center in the holes for them. Being off center in the holes isn't noticeable when the wipers are reinstalled. The two best options are 1. Open the indention's for the wipers or 2. bend the arm to keep it from sweeping off the side of the window. I think bending the arm will be the easiest and will look better than trying to change the cowl itself.
