Window wiper crashing into A pillar

[Scouser]

Every now and then, my window wiper is crashing into my driver side (RHD) A piller when driving at speed.

Anyone else notice this?

Replaced the blade but problem persists.....

Lift the cap (item 16) on that one wiper blade and check and see if the nut has come loose.

If not that then... Check the tightness of the wiper link screws - I've heard of these coming loose before too.

Thanks Loren. I will try that tommorow. Will let you know.

Finally got to tackle this last night. It was a pain to do as I had to remove the front bonnet then the black plastic bits (joing the battery cover) would not unscrew. I ended up busting the screw grommets. Will have to buy new ones. No big deal.

But I checked the wiper nuts and all the wiper linkage nuts. They were all tight. So cant see anything wrong there.

At speeds over 80mph if it is heavily raining the wiper occasionally bangs into the A pillar...especially if there is a gust of wind. Weird and annoying.

Take the blade off and inspect the mounting shaft. Older Porsches were splined but I've never had to take a 996 blade off yet.

I replaced the blades thinking it was them. It's weird. They work fine normally. It's just when driving at high speed in heavy rain when its high wind. A gust will cause the blade to slip into the pillar.

I know it sounds weird but I think it may be Rejex!
