Nez_Pottage Posted June 29, 2023 Posted June 29, 2023 I have a T32 1.6Tdci Auto that usually works like a dream unless in heavy traffic in warm weather. When I sit at lights, in drive, with the foot brake on, I can get the car to overheat, but once i start moving it cools down fairly quickly. When it does hit Red, the cooling fan is not kicking in at all. I can pop the bonnet and the fan is static, even though the car is on the edge of stopping from overheat. My garage says out of the 4 cables to the fan, two have power showing, so they have tried a new relay today. They can't get the car to an overheat temp, but the fan still does not kick in at all, ever. Can anyone tell me on these model should the radiator cooling fan be on when the Air Con is turned on, as there doesn't seem to be an air con fan around the same area. If not, and other good troubleshooting methods? Also to note, when sat in traffic, the air con goes pretty poor, but then is a lot better when moving again, probably down to airflow also. As I saw, normal driving all seems well, but an hour in traffic in London will nearly kill it every time. My trick is to drop to neutral when idling which helps get me by, but I need help troubleshooting the fan / relay / other without the expense of a full Nissan garage diagnosis fee.
