Jaguar F-Type Forum

I've also thought that the washers on the ftype are the worst I've come across, very ineffective, perhaps I need to do some checking of pipes...

I've always been impressed with the way Jaguar does washers - having the jets above the wiper arms and squirting on the upstroke seems genius to me. Maybe your jets are clogged up.

They just don’t seem to clear the top part of the windscreen unfortunately! Just had a new wiper arm fitted as the pipe had worn out, obviously Jaguar don’t just sell a piece of pipe. You have to buy the whole new wiper arm. Luckily under warranty.
The idea in principle is good but it is pretty crap in practice.
