Hi just got my new baby less than a week.. I hv noticed that the wipers are making noise when applied..(it's not the high pitch squeaky noise.) It seems like the blades are "slugghish" during wiping... and it's making the "ba, ba, ba" kind of noise when wiping.. When I apply the windshield fluids, the noise seems to go away and the wipers do a wonderful job.. however, when no fluid, under regular rain...the noise resumes.. is this unusual? or just the rubber of the blades are just too new/hard? I think i shud take the car back to the dealer for a quick look.. w. bc canada
