Hi,

We've had our volt for a few years now, and we've noticed at consistently when we're using the windscreen wipers and there's plenty of rain being swept from the glass, both blades seem to pull the water back onto the windscreen after sweeping the water to the edge. It's often that after the blade moves back from the edge of the windscreen to return to the centre of the glass to sweep again, about 6 inches wide or more of water is pulled back towards the drivers field of view, and also the same on the passenger side.

It's rained so infrequently here over the last year that I'd forgotten about it for awhile, but my wife mentioned it to me again today, and we're wondering if it's an adjustment, or if they're all just like that.

Does anyone have any thoughts? I've had a look through the forum and I couldn't find any other posts raising the issue.

Thanks,

craby

Does it do it with new blades as well? The only adjustment that can really be made is to bend the wiper arm so it applies more pressure against the glass. That said however, the metal arm portion of the volt wiper arm is quite short, and pretty stiff unlike older cars, so not sure you can really do much there. My best suggestion would have to be blade replacement.

When the blades are nearly vertical, the wind being pushed to the side flows over the wiper blade and curls back toward it and the center of the windshield, pulling some of the water along with it. As soon as the blade is far enough away, then the wind starts blowing the water off to the side again. It's normal and not worth fixing.

I experience this as well.

More so when I had "universal" left and right wipers
A LOT more when I had the left and right wipers reversed (the airfoils were in the wrong place)
Less so when I had true left and right wipers on the car in the right positions.

Gen 1 Wiper reference here

It always happens at least a bit to me.

Maybe the blades have lost their flex sitting unused in the Brisbane sun, and don't want to 'flip' when they reverse direction.

In addition to what others have said, check whether or not the windshield is dirty along the vertical edges where the wipers reverse direction as well as the wiper blades, themselves.

More important, see if it does it at all or as much when you're not moving.

Hi again,

They're all good suggestions. The blades have been replaced a few times and it's continued to do it, so I'll see whether or not it does it when the vehicle isn't moving, and I'll double check that the wipers are on the right sides. I was pondering after reading your replies whether or not its a function of the airflow over the windscreen. I'll do some checks while the car's not moving and see how it goes. The hose should do the trick.

More news shortly.

regards,

craby

I'm pretty sure it's a function of the aerodynamics when moving, but I've never tested it.
Honestly I use RainX (going to try Aquapel soon) and rarely actually use the wipers when at road speeds.
