My wiper only wipe half of the windshield
 

Not sure if the arm is slightly bent, but the wiper only clears the top half of the windshield. I replace the blades any i still get the same result...i thought the hook that the blade slides in was supposed to be face down toward the hood but pics i've seen show them up so....I'm stuck in the rain...What do you think...?

you need to get reversed blades the only place i found them was oreillys

makes perfect sense...just put some picks up check them out...!!!

^^^ agree, the r stands for reverse, trico part # 249R acdelco part # 82249R
