Hi pw1962, assuming that the blades and mounts are in good condition and your not using replacement blade inserts, or washing up liquid in your screen wash the first thing to check is that the glass is clean as a build up of silicone is usually the culprit, try cleaning the glass with vinegar, meths or use a good quality screen wash neat on a cloth and clean the glass.

If thats no joy the chance is the wiper arm(s) are slightly bent so the blade is not being presented perpindicular to the glass, adjust them using an adjustable spanner across the flat part of the arm and twist so the blade looks like its at the correct angle, you might need to try this a few times to get it spot on.

Its usually caused by automatic car washes bending the arms ..... use a good quality screen wash or an additive called "clearalex" which will keep the glass free of any build ups .... hopefully problem solved.

hope it helps :)

Great, thanks for all the advice. I take it that if I need to bend the arm it only need to be just off 90 degrees?

Yes, you will only need to bend the arm very slightly, just so the blade is sitting at 90 degrees to the glass, if its very far out or the spring in the arm is weak you may be as well to change the arm .... hopefully not, as the arms are about £50 each from Renault.

Hope it helps :)
