Today I used the wiper blades once to clear the windshield. After driving five minutes or so, I try to give it another wipe and nothing happens. Once I get to my destination, I found the fuse was blown. So I pop another 20A one in, and as soon as I turn the key to the on position (before starting), it blows again. And again. Then I try a larger one, 30A. It blows just the same. Before I go replacing everything, what's good to look at? I figure it's the wiper parking switch (wherever that is :)), since it happens immediately and the blades aren't parked completely. Should I just get a new motor/junkyard motor? Is the park switch within the motor assembly usually?
