I have 2002 Clio sport 172. One day I was driving to the shop and everything was fine and when coming back straight after starting the engine, the fan has gone to maximum speed and temperature. Since then it is imposible to adjust anything in the climate control. All controls are working and all is displayed but it doesn't work. You can lower and raise the temperature and fan speed on the controls and display but the fan is always at it's maximum speed. I can only switch it off by taking out the fuse. Checked all the fuses and no idea what it can be. Any thoughts?
