My heater is not working properly , the car is at normal running temperature, midway on the coolant and 200f on the oil temperature but I need the climate set to full to get the car warm , it does blow hot air though so water is going through the matrix

I dont think there is a mechanical issue but an issue with the valve that controls flow though the heater matrix.

The car last had a coolant change about 2 years ago , but its been getting worse for a while , its certainly not air in the system , its a 2012 touring with 34k on it

Earlier Nissans have a built in diagnostic mode but I'm guessing the z doesnt ?

I've read the code with an obd reader and its all clear

Any ideas or do I need to take it to a dealer for a consult check ?
