Not the performance enchancing kind, im afraid, just the climate control kind. The fan in quiestion resides in the dash of my car. The problem is that on speed number 4, while moving quite a bit of air, has a terrible noise that sounds sort of like a harley davidson. On speed 3, this noise is not noticable but it doesnt move much air either. It blows enough to keep the windows defogged and to keep me warm, but its weak enough that i cant really feel it on my feet and i find myself moving all of the sliders all the way to the right. While its bearable, i would like to have more control over it than just one speed that is barely adequate.
Has anyone had htis problem before? Is there any way i can fix it, or is replacement the only answer? Any help is appreciated.
