Do not confuse the air conditioning , heating and ventilation of this Toyota Mr 3. Heating and air conditioning are systems that offer the possibility of decreasing or increasing the temperature. The first by means of the heat produced by the engine block, and the second with the help of a liquid refrigerant . Your ventilation is all the ducts and mechanisms that allow the air to reach the interior. The fundamental component is the kicker that emits air into your vehicle. If the air is coming in little or not at all, it is probably a ventilation problem. We will see in this article how ventilation works, in order to better perceive the problems and assimilate the technique to solve them.ventilation-problem-Toyota-Mr-3

How a ventilation works on a Toyota Mr 3

The ventilation is primarily used to circulate the air in the passenger compartment of this Toyota Mr 3. Concerning the blower, the latter is often made up of a resistance, a turbine, and an engine. The more the total resistance of the circuit is lowered, the faster the turbine operates. By turning the knob in the passenger compartment, the resistance is lowered.

Toyota Mr 3: common ventilation problems

Dirty air ducts

If the ventilation works but a small amount of air is entering the passenger compartment of this Toyota Mr 3, it is plausible that these air flaps are blocked. With the aid of screwdriver flat, it is possible to remove the covers from the air vents. It will suffice to check inside if they are blocked. If ever this is the case, it is possible to dust them off, but also the valves.

Dirty cabin filter

When you discern effluxes and the ventilation lacks intensity, the problem probably comes from the cabin filter of this Toyota Mr 3. The latter clogs and accumulates bacteria as time goes by. It remains totally common that it is clogged, it is there to filter the air that reaches you. There is no instruction from the manufacturer on when to change it. It is only advisable to take it apart and check its condition. If it is completely dirty, it will need to be replaced.

Resistance of the blower HS

If the ventilation adjustment of the Toyota Mr 3 is working poorly, or even not at all, it is probably related to the resistance. This resistance allows to increase the voltage to be able to increase the speed of the turbine. An inconsistent ventilation malfunction is undoubtedly due to a concern for resistance. This small electronic chip is complicated to repair. It will have to be replaced.

HS blower motor

There are several fairly common issues with the kicker. The brushes are worn. Over the years, they will be able to deteriorate and generate electrical faults. Your fan may run haphazardly or not at all. It also happens that the concern comes from bearings fan motor. If the ventilation makes a high-pitched noise, comparable to rusty mechanics, its bearings may need lubrication.
