How a heater works on a Nissan Maxima 4
In the middle of winter it is our best ally on the road to go to work. And when the latter does not activate, we notice it ardently. In this case in order to know where the malfunction came from, you need to understand how it works on the famous Nissan Maxima 4, or at least the main lines. The heating uses heat from the engine block to increase heat from the personalised tour, then very often from the cooling system. Therefore this system has several functions. In addition, the fan system, so that the heat arrives in the cabin has a double system. It's the ventilateur which sends the heat as soon as the car is running at low speed or or not, then it is the speed of the car which sends the heat once you drive faster. Pretty well thought out right?
Recurring heating problems on a Nissan Maxima 4
Broken thermostat
The concept is elementary, in the case where the thermostat which regulates the temperature does not really understand the degree of heat of the cooling circuit, the latter is affected. Even if the thermostat of the famous Nissan Maxima 4 still does not work properly, the heating will still work. Quite simply because the heat produced by the engine block will increase progressively, and the water circuit in the same way, whether it is regulated or not. The only concern is that you cannot really configure the heat emitted.
Air shutters blocked on the Nissan Maxima 4
It is a dysfunction that happens quite frequently. 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 4
As you will have understood, the fan is effective only at low speed and in neutral. If this heater does not send heat at low speed at all and you can still hear noise, it means that your fan is probably running out. A priori, thanks to more speed the heating of the famous Nissan Maxima 4 will be able to work. If the fan never works in any way, it should be replaced by a new one.
Blocked hoses
Its clues are relatively obvious. In case your heating turns and does not heat or very little, the malfunction is probably due to the hoses. These clog more time passes and do not allow hot water to reach your heating of the famous Nissan Maxima 4. In this case, wash the hoses or replace them with new ones.
Air pocket in the circuit of the Nissan Maxima 4
The syndrome is the same as that of the hose lines. If ever air pockets are inserted inside the circuit, hot water will also have difficulty accessing the radiator of the heating of your Nissan Maxima 4. In this case, you just have to purge the circuit.
Conclusion
You now understand where the malfunction may come from. By cons it is possible that the problem is from elsewhere, such as the air duct of the famous Nissan Maxima 4 obstructed, or even a defective valve, but it is unfortunately less frequent.
