The part that is holding the wipers is rusted and I want to replace them. Is it possible to replace? If so, how much and where can I get them?
Replacing the wiper arms are a breeze.go to local auto parts store and buy both sides,they'll show you how to replace the set.Gave you a generic site on how to replace them.You can Google your vehicle by make and get a better how-to-do.
Advance Auto or Auto Zone should carry them and they should change for you too for free. If I remember correctly there's a clip holding it on to the knob but it wasn't that easy to remove. I'd definitely try those two places first.
