    Looking online it could be fuses, bad earth or you dont have the correct windscreen for auto lights/wiper

     

    "The DTC error indicated U2030-0F, rain/light sensor communications error. I replaced the sensor and checked the wiring between the sensor and GEM module, no fault was found.

    I eventually contacted the company that replaced my windscreen and I got them to install a genuine FORD windscreen and my auto lights and wipers functioned properly again.

    What we found is that the sensor has an IR mark on the back and it requires a IR windscreen, which is also clearly marked on the bottom of the windscreen."

    If the screen was fitted through Autoglass or similar, they offer warranty on stuff like this.  When my screen was fitted the tech broke the sensor, they came back and fitted a brand new genuine part FOC.
