Hey all, My wife has a 2007 Edge and the rear wiper is starting to fail, so I'm trying to pinpoint the failure point. Some details: When you turn on the switch, it sometimes works, sometimes doesn't. Fluid pump still works every time, arm just doesn't move. When it doesn't work, you can still hear the relay in the back clicking. Tends to work better after car has been running for a bit. When it does operate, it doesn't seem sluggish. My best guess is a sticking motor. Thoughts?
