The rear wiped on my car is utter cack. I've tried three new blades and it still misses loads in the middle when it wipes.

It looks different to the one I had on my 02 plate which worked fine, this one has a smooth arm with the blade inside it. Anyone know of a proper blade that works, or is it better to change the whole arm, don't care if it looks a bit poo just want a clear window now!

Try a replacement arm, you current one may not be applying sufficent pressure on the glass.

You have to get the proper blade for that type,from a dealer or TPS as the blade is curved,staight replacements miss the middle as you have described.

Just de wiper it mate the rear wiper is crap looks alot better without it aswell
