Hi all,

 

My front wiper has decided to suddenly start tapping on the A pillar, no idea why?!

 

Wiper blade is fine and arm doesn’t feel loose. Any ideas? Thinking it may have moved on the spline due to icy window friction??

 

Any advice gratefully received.

 

Thanks. 

You are probably correct.

 

Loosen the securing nut, realign it, tighten properly and test, test again on high speed with a very wet screen, be prepared to perhaps make a minor adjustment if it touches at during a combination of high speed, heavy rain, high winds.

 

Lossen & retighten the other one while you are at it.

I have experienced this before when there was something on the bottom of the windscreen that the wiper wasn’t running over smoothly causing the top to kick out and hit the A pillar. A good clean sorted it out. 
 

I would be very surprised if you managed to move it on the splines. You can’t get those suckers off even when you want to

The arm can bend if say you let ice and snow build up at the bottom of the screenand it keeps running into it. It is also very close to the pillar when it stops. I have had to carefully bend mine a few mm the other way in the past to stop this. Indeed my first 2010 Yeti came doing this all the time the screen was almost dry and I had to move it on the splines one spline.

 

The other issue is if the screen is a bit dry it judders across it and this can promote a flick at the end of the travel hitting the pillar edge.

I don't know why yours has stated to hit the A pillar but when I bought my latest Yeti the wiper was hitting the A pillar. The salesman took the car around to the workshop where they adjusted something on the wiper linkage or so the salesman said, I didn't see what they did.

It might be worth looking under the bonnet in case part of the linkage has worked loose.

I've had that happen, when a hedgehopping pheasant hit the LH blade. So it can be done!
