How a heater works on a Nissan Maxima 3

Heating in winter is a definite asset on the journey when going to work. And when it doesn't turn out well, you notice it intensely. So to understand where the problem comes from, you have to understand how it works on this Nissan Maxima 3, or at least the main lines. The heating use the engine block temperature to warm up the personalised tour, then generally the cooling system. In this way it duplicates. In addition, the fan system, so that the hot air reaches us also has a double use. It's the ventilateur which sends hot air as soon as the car turns at low speed or is stopped, then it is the speed of the car which will send hot air when you drive faster. Well designed, right?

Recurring heating problems on a Nissan Maxima 3

Broken thermostat

The concept is affordable, when the thermostat which regulates the temperature does not really capture the degree of heat of the water circuit, the latter is affected. Even if the thermostat of this Nissan Maxima 3 does not work well, the heating will still work. Because the natural temperature of the engine block will increase progressively, and the cooling circuit at the same time, whether it is regulated or not. The only concern is that you will have trouble regulating the heat emitted.

Air shutters blocked on the Nissan Maxima 3

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 3

As you will have understood, the fan is only used at reduced speed or the engine off. If the heater never sends heat at a reduced speed at all and yet you hear its noise nevertheless, it means that this fan turns out to be probably screwed up. As a general rule, thanks to the high speed, the heating of this Nissan Maxima 3 should work. If the fan does not work it is better to replace it with a new one.

Blocked hoses

His symptoms turn out to be rather obvious. When your heating turns and does not generate little or no hot air, the problem probably comes from the hoses. These get dirty over time and do not allow hot water to heat up this Nissan Maxima 3. So, clean the hoses or install new ones.

Air pocket in the circuit of the Nissan Maxima 3

The syndrome will be identical to that of the durits. If ever air bubbles are inserted in the circuit, the hot water will also have problems to access the radiator of the heating of your Nissan Maxima 3. So, it is necessary to purge the water circuit.

Conclusion

You now know where this worry will arise. However it is possible that the problem comes from elsewhere, such as the air duct of this cluttered Nissan Maxima 3, or a deficient tap, but this is still more rare. You can write a comment in case this post served you. Enjoy the road!
