I had kind of the same problem except it seemed to only have one speed & when I turned them off, they stopped immediately instead of coming to rest down at the bottom of the windshield. I pulled the wiper motor & removed the top case. Underneath you will see a set of 3 brushes. Look for a broken wire or connection. I had a bad connection & just soldered it back to where it belongs. Wipers work fine in low, high & intermentent speeds & they now park as they were designed to do. Hope that helps. <img src="/forums/images/graemlins/patriot.gif" alt="" />
