Well to be honest I really do not see the dealership putting them on !!! for what???? now when I bought my first 04 it came right off the truck with the deflector on both sides so now what???? and when I bought my 05 it came with both deflectors also, different dealer though and not to mention why is there a part number with the deflector, if they did not put them on why offer a replacement, something here is way wrong, dealerships do not put stuff on cars and just give it to you for free and there was nothing on my invoice showing an extra charge for deflectors on the wipers. I have worked dealerships as a tech for 27 years and have not seen to many dealers jusy giving out freebies
