Had a problem with the coolant temperature needle not moving so on recomendation changed the coolant temperature sensor with a genuine green on from TPS. Topped the fluids after fitment and hey presto the needle moved and stayed at the recomended 90 degrees. However now when i have the climate control on it dropps down to the minimum and when i switch it off it rises to the magical mark? I have topped up the fluid and also flushed the coolant out (only g12 nbeing used ) The climate works as it should when asked ???? Just a little confused .
