The outside air temperature display on my williams 2 is a bit dodgy. It sometimes reads -30 or even +50 degrees and will often flash, then it will return to normal the next time i get in the car. Im thinking that it could be a bad earth/connection or a faulty sensor somewhere. Does anyone have any wiring diagrams for the clio? Or know where the temperature sensor is? Had a look in the Haynes manual, but found out they didnt cover the williams.
