Rear wash/wiper arm

[Pablobongo]

Hello,

just fitted an "aero style" rear wiper blade, only to find that it doesnt really make enough contact with the glass to be efficient. Tried bending the arm slightly, and it is better, but still not that good. Has anyone changed the spring at the base of the arm?, if so, which alternative spring did you use?.....I have half a mind to change the whole arm for a more modern looking one from a different vehicle....just have not got the time to raid any local scrap yards at the moment!

If you experiment with a new rear wiper arm/blade combo from another vehicle, the size of the splined spigot the arm bolts to is critical if you don't want the arm to slide off the spline.

Best to grab a bunch of likely wiper arms and actuall fit them one after the other at the scrappy, and test the wiper sweeps as it should quite few times without it slipping off the spline.

I went for a circa 2003-5 Mazda Demio rear wiper arm/blade courtesy of Mikexgough

It gives a slightly smaller "sweep" but is firmly planted on the rear screen, and looks more modern.

Thanks for the tip BDC, will look into it more seriously in the new year....

Aye... when it's a bit warmer!

If you bend the wiper arm back you can see a hooked piece of wire that sort of curves round the pivot on the arm where it bends up & attaches to the spring in the arm recess.. I managed to remove the wiper arm, take the spring assembly apart & close the angle on the hook/like a couple of millimetres to re-tension the spring... Works a treat! (If it hadn't, i would have gone for Mr Cain's idea!!)

I will try this, both this & my previous Freda have been useless as far as the rear wiper is concerned, I have bent the arm to effect more pressure which worked a treat on the Freda but it has had little effect on this one.

The airflow at the back may well have eddies. If there is a spoiler on the blade it might even lift it rather than forcing it down as it should on the front screen.
