I never could figure this one out and it sucks. Wiper blades on my truck last no longer than a month or two before they no longer function and just streak/smear water/dirt/condensation on my windshield usually making it harder to see than if I didnt use them at all. I know the main reason is because I have to park my car in the open with no canopy to protect against the sun but here is the thing that bothers me. My wife parks right next to me and suffers the same conditions, we can buy the same type/brand wiper blades at the same time and hers still last and function properly for months on end. I have a S10 Pickup, she has a Dodge Caravan maybe it has something to do with very minor details like the angle of her windshield or the amount of pressure the springs are putting on the wiper blades? Im always stuck in the morning when my windshield is fogged up I have to wipe it down by hand and wait for defrost to kick in or it will fog back up as I drive. In the light rain I cant use them because it smears horribly and makes it hard to see, only in heavy rain is it viable to use my blades. So anybody want to key in on hints/suggestions/stories?
