Re: wipers mist setting
Here's a fix for noisy wipers, might be your problem, might not, but worth checking...... as its free!
First wet the screen and now turn on the wipers and then turn OFF the ignition when the blades are half way thu their sweep (45 degrees). Now look at the edge of the blade. They should be trailing the arm, i.e. if the blade is going up the screen the edge should be towards the bottom of the screen. If they are, then active the wipers again and stop them on the way down. This time the edge should be pointing at the top of the screen.
If they are not or one of them is NOT then it's being pushed across the screen NOT being pulled and this will give rise to noise.
The cure -Allow wipers to sweep across the screen and when they are at 45 degrees (halfway) switch OFF the ignition. Now remove the blade assembly so that you are left with just the bare arm. Lay this on the screen and check to see if the end of the blades retaining hook lays flat on the screen. If it doesn't then you need to twist the arm so that it does. To do this hold the arm about 1/4 way up from spindle in a pair of grips, protect the arm with a cloth and then using another pair of grips 2/3 the way up apply a rotating motion.
Lay the hook on the screen again and recheck. When satisfied, refit wipers and try again. The blades should then change direction and trail the arm on each sweep.
