We have a 2017 Nissan NV 3500 that overheated today while sitting parked with the air conditioning running. Fortunately my teenagers shut it off as soon as it happened.
The cooling fan is spinning but does not appear to be going into high speed when the temperature comes up. The temperature gauge is reading through the ODB reader as well as on the dash. It does look like the temp on the dash jumps around a little bit but I don't know if that's just the thermostat cycling. The fan fuse is not blown. Any ideas?
