Are the wiper arms wiping the screen correctly. Re when the wiper arms go up to wipe the screen. When they return to their normal position. Do they go down past the windscreen rubber or below the level of the glass. Then back up. Because it maybe that you need to remove the offending arm and re-align it. By operating the wipers and turn them off. Then see precisely where the arms sit. It maybe that one arm or both need to be repositioned in order to fix the problem. Someone may have replaced the wiper motor or wiper motor mechanism and not put them back right. It’s difficult to diagnose without seeing the actual problem.
