I rarely use the wipers but mine work fine. In the past I was a Rain-X guy (my go to for the last 30+years) and now I go the extra mile and polish all the glass with CarPro Cerimide and use a long lasting coating. Now the rain just washes away faster than the blades can hit it.
My car was ceramic coated with Modesta and that's when the chattering started. My detailer is attempting various fixes but so far no luck. Might have to remove the coating from the windshield after all.
Did some searching on the Bosch Aerotwin wipers for LHD vehicles 3 397 009 00B / A989S - can someone confirm if this is the right number ?
