Hey I pressure washed under my rear bumper and they quit working. Unplugged all of them and none of the connections were wet as I had put dielectric grease in them when I put the bumper on. Called ford and they won't tell me if there is a way to find out if it's a bad sensor or short in wiring or what. So, is there a way to diagnose it myself? Or do I have to take it in? Thanks!!
