I have a 1998 C 1500 pickup. My windshield wipers have a mind of their own. Sometimes they work, sometimes they don't.When they do not work, I can turn the switch on or hit the wash switch and you can hear a low pitched buzzing sound but thats it. When they do work you cannot hear this sound. What could my problem be??
