My 2008 Holden Colorado has very noisy wipers and it's not the blades that are the issue – they were just fitted new. The mechanic said it is the linkages. It sounds like rubber against rubber. Can you help?
It’s not likely to be the linkages. The blades are the usual cause of such a noise, and it’s mostly because they don’t flip over when the wipers change direction at the end of each sweep. Try something like Rainex on your screen; that usually does the trick.
