I have a 2003 Ford Crown Victoria and when i turn on my windshield wipers they skip and scrape across the windshield. I have replaced the wiper blades 4 times and have used different blades each time. I have used Anco, Trico , and since i work for a Ford dealer i have used OE Ford blades. I have had no luck getting good wiper blade usage. Is it possible that the wiper arm s are pressed to tight against the windshield?
As u described, only high speed makes the difference. I would start with checking driverside wiperblade and arm control to any damage, bent etc.just adjust the arm so high winds don't blow the wiperblade off the windshield.try this first
Try thoroughly cleaning your windshield, then applying some RAIN-X.
there is a spring that should regulate the tension for the windshield wiper sound like thats the problem or you have something on your window and if you work at a dealership just ask a mechanic
