Re: [alfa] GTV-6 wipers: swept area

["Paul Bayly" <thebaylys@xxxxxxxxxxx>]

This sounds like wear in the mechanism somewhere.  As the motor simply goes
round-and-round with the bellcranks turning the rotary motion into linear,
there is no way to vary the 'sweep' of a wiper arm unless there is slop
somewhere.

Sounds similar to my Landcruiser.  Problem was a collapsed nylon bearing in
one of the rods under the cowl.
