Anyone know if it's possible to adjust the sweep of the drivers side windscreen wiper. The wiper on mine returns about 2 inches short of the screen A pillar right leaving a really annoying dirty wet patch in my eyeline. I've tried taking the wiper off and moving it around 1 spline but when I do that it hits the wiper sweeps too far and hits the A pillar. 

 

It's on a 206 Rx400h by the way.

I don't know how to adjust it but I have the same problem and it annoys me too, especially when traveling on muddy country roads!  I wondered about moving the wiper position on the spline but I won't bother given your experience as I assume the 3RX range of adjustment is similar to the 2 RX.

I'm tempted to get a spare wiper arm and see if I can bend it slightly, only needs an extra inch of sweep to be perfect.

Maybe contact Lexus for their advice?

The wiper arms should be set to a mark that is on the windscreen, a small dot.To do this you will have to remove the wiper arm and sand/file the existing high points from the wiper arm and reposition on the splined shaft from the motor. This is tapered and will recut the splines in the wiper arm as it is ally on steel.

I used to build Toyotas and had to do this a few times when the wipers were fitted to motors that had been activated prior to the arms being fitted.

    1. 1. If you were to consider buying a Hybrid model over 5 years old, would you be worried about the reliability of the Hybrid system?


      • Not really as Hybrid systems are always reliable
      • Not if it had a Manufacturers Warranty on the Hybrid system
      • I would not buy a Hybrid model over 5 years old
