- 2003 NBX
Gentlemen,
Maybe you can help me out?
I have a 2003 NBX with a 4.0 currenty running with minimal heat.
It's never really had great heat. Last year it started making the blend door actuator click. Changed that out. Door is working as the temp is changing with the blend door actuator control.
I threw a new thermostat at it (second time in 2 years)but no change.
Using my DMM with a thermometer attachment it blows about 65 degrees on fan setting 4 (outside temp was -25). Temp at the vents increases with engine RPM. The rear heater is the same. So I beilive it is not a problem in the heater housing?I took the fan clutch off and drove it and it made heat, 95 degrees actually, it also over heated.
So I put a new fan clutch on and now it is cold again.
Engine temps (after driving 5 miles)with a infra-red thermomter are 120 going into the heater core. 165 at the thermostat housing.
I am not sure where to go next?
Thanks
