How a heater works on a Nissan Maxima

In the middle of winter, heating is essential on the road to go to work. And when the latter does not work well we notice it ardently. So to understand what the problem came from, it is necessary to understand how it works on this Nissan Maxima, at least its principle. The heating uses the temperature of the engine block to be able to raise the temperature of the personalised tour, then generally the cooling device. In this way this system has several functions. In addition, the fan device, so that the air reaches us also has a double use. It's the ventilateur which sends the air as soon as the car is running at low speed or or not, then it is the speed of the car which allows the air to be sent when you are traveling faster. Well designed, right?

Recurring heating problems on a Nissan Maxima

Broken thermostat

The concept is affordable, in the case where the thermostat which regulates the heat does not capture the temperature of the water circuit well, the latter is affected. Even if the thermostat of this Nissan Maxima still does not activate well, the heating will work normally. Because the temperature produced by the engine block will gradually increase, so will the water circuit, even without a thermostat. The only concern is that you can't really set the air temperature.

Air shutters blocked on the Nissan Maxima

It is a concern that happens quite regularly. These shutters, which allow you to direct the air or adjust the intensity, sometimes get blocked over time. To remedy this it is simple, remove the cover and look inside how it was done. Activate the mechanisms to see where it is blocking. Put a little WD 40 to lubricate and voila.

Faulty fan on the Nissan Maxima

As you can imagine, the fan is effective only at low speed or in neutral. If this heating system no longer emits air at low speed but you can still hear its noise, the fan turns out to be probably screwed up. If all goes well, thanks to more speed the heating of this Nissan Maxima should work. Assuming that the fan does not really activate it will have to be changed.

Blocked hoses

Its signs are rather simple. As soon as your heating works but does not create heat or very slightly, the problem probably comes from the hoses. They get dirty over time and do not allow hot water to heat up this Nissan Maxima. In this case, remove dirt from the hoses or replace them with new ones.

Air pocket in the Nissan Maxima circuit

The symptom happens to be identical to those of the hoses. If small air pockets are introduced into the circuit, water also has problems reaching the radiator of the Nissan Maxima heating. In this case, it is necessary to purge the circuit.

Conclusion

You now know what the problem will come from. However it is possible that the concern comes from the other hand, such as the air duct of this cluttered Nissan Maxima, or even a deficient tap, however it is unfortunately rather rare.
