How a heater works on a Nissan Maxima 2
When it's cold it's a definite asset on the road when going to work. And when it is no longer activated, it is easily noticed. In this case in order to find out where the problem comes from, you have to understand how it works on this Nissan Maxima 2, at least the basics. The heating uses the engine block temperature to heat the personalised tour, and very often the cooling system. So it is duplicative. In a similar way, the emission system, so that the air comes to us also presents a duplication. It's the ventilateur which sends the air when the car is running at low speed or or not at all, and it is the speed of the car which will send the air when you are going at high speed. Well designed, right?
Recurring heating problems on a Nissan Maxima 2
Broken thermostat
The idea is simple, assuming that the thermostat that adjusts the temperature does not really understand the degree of heat of the water in the circuit, the whole circuit is affected. Even if the thermostat in this Nissan Maxima does not work well, the heating will work normally. Quite simply because the temperature produced by the engine block will increase over time, then the water circuit in the same way, even without a thermostat. The only problem remains that you will hardly be able to modify the heat emitted.
Air shutters blocked on the Nissan Maxima 2
This is a problem that occurs 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 2
You have now entered, the fan is useful only at low speed and the engine off. If ever the heater does not emit too much heat at low speed and yet you still discern noise, the fan is likely to be broken. In principle, thanks to more speed, the heating of this Nissan Maxima 2 will be able to work. If the fan does not work, it will have to be replaced.
Blocked hoses
Its symptoms will be quite obvious. When your heater works but does not generate hot air or very little, the problem is most likely with the hoses. The more time passes, the latter become dirty and do not allow hot water to reach the heating of this Nissan Maxima 2. In this case, clean the hoses or put new ones.
Air pocket in the circuit of the Nissan Maxima 2
The syndrome is sometimes identical to that of the hoses. If ever threads of air are inserted in the circuit, water at high temperature similarly has difficulty accessing the heater radiator of the Nissan Maxima 2. In this case, it will suffice to bleed the circuit.
Conclusion
You now know where the problem could arise. That said, it happens that the problem comes from another part, for example the air duct of this Nissan Maxima 2 blocked, or a faulty valve, but this is still rather rare.
