| When you open the bonnet there is a rubber pipe just beneath the wiper in the middle, check that this is connected securely. I had a whistling sound before but only when excellerating. this pipe had come loose and once replaced sound disappeared.
May not be your problem as Ive read other threads about Wipers, Window Trimmings all making noise. Check all the windows are closed properly, sounds idiotic but if you only drive the van you never think of the passenger side window being slightly open. |
