Let's not confuse the air conditioning , heating and ventilation of your Toyota Supra Mki. Heating and air conditioning are mechanisms that lower or increase the air temperature. The very first with the help of the heat produced from the engine block, and the second with the help of a liquid refrigerant . Ventilation is all of the channels and devices that will allow air to enter the passenger compartment. The essential element is the kicker which propels the air within your vehicle. If the air barely or not at all reaches the air, it is certainly a ventilation malfunction. We will discover in this file how a ventilation works, in order to better discern the dysfunctions and understand by what means to resolve it.ventilation-problem-Toyota-Supra-Mki

How a ventilation works on a Toyota Supra Mki

Ventilation initially serves to regenerate the air in the passenger compartment of your Toyota Supra Mki. As for the blower, it generally consists of a resistor, a turbine, and a motor. The lower the total resistance of the electrical system, the faster the turbine operates. By turning the knob in the passenger compartment, the resistance is therefore reduced.

Toyota Supra Mki: regular ventilation problems

Dirty air ducts

When the ventilation works but little air reaches the interior of your Toyota Supra Mki, it is possible that your air shutters are obstructed. Thanks to a screwdriver flat, you can remove the covers of the air vents. It will suffice to check in if they are congested. When this is happening you can dust them, but also the shutters.

Dirty cabin filter

When you perceive effluxes and the ventilation lacks intensity, the malfunction probably comes from the cabin filter of your Toyota Supra Mki. It clogs and piles up bacteria with time. It is completely common that this one is dirty, it serves to clarify the air which reaches you. There is no instruction from the manufacturer as to when to replace it. We just advise you to remove it, check its condition. When it is particularly black, it will be better to change it.

Resistance of the blower HS

When the ventilation adjustment of your Toyota Supra Mki malfunctions, or not at all, it is probably related to the resistance. This resistance increases the voltage to increase the speed of the turbine. A suspicious ventilation malfunction may be linked to resistance malfunction. This little microchip is difficult to troubleshoot. It will have to be changed.

HS blower motor

There are two relatively recurring malfunctions on the blower. The brushes are worn. Over time, they may deteriorate and generate electrical faults. The kicker may work randomly, or even stop working at all. It also happens that the dysfunction comes from bearings of the fan motor. When the ventilation makes a sharp noise, like a rusty mechanism, it can happen that its bearings lack lubrication.
