Any tip on how to fix it?? My car is only 7 months old, and I have noticed while wiping it make a loud noise (it's not those motoring loud noise)...more like wiping scratching noise "brrrrkkk" especially when the screen is moving downward. I try to remove the blade, clean it, and put it back....still the same problem. Dont tell me it's time for me to change a new blade set?? or could be the motor issue? How long do normally a new set last?? I thought it should last at least a year?
