Windshield Wiper/washer problems of the 2003 Hyundai Elantra

01/10/07 windshield wiper failure to clear windshield when using the wipers to clear snow from windshield, the middle of both wipers would not clear snow enough to see out in certain spots. Winter blades had just been installed. I stopped the car and wiped them off. Blades continued to skip over certain spots on windshield. This has happened numerous times. I agree with others statement that maybe this car is not meant to be driven in the snow, or at least wipers not meant to clear off snow as it lands on windshield. I too, had previously completely cleared buildup of windshield before starting out.
