Do not confuse the air conditioning , heating and ventilation of your Toyota Supra Mkiv. Heating and air conditioning are mechanisms that give the possibility of lowering or increasing the air temperature. The very first by means of the heat emitted from the engine, and the other with the help of a liquid refrigerant . Your ventilation is all of the circuits and devices that will allow air to enter the vehicle. The main element is the kicker which sends air into your automobile. In the event that the air arrives very little or not at all, it is probably a malfunction of ventilation. We will see in this post how ventilation works, in order to better perceive the dysfunctions and assimilate the technique to remedy them.ventilation-problem-Toyota-Supra-Mkiv

How a ventilation works on a Toyota Supra Mkiv

The ventilation is used first to circulate the air inside the passenger compartment of your Toyota Supra Mkiv. Regarding the blower, the latter usually consists of a resistor, a turbine, and a motor. The more the total resistance of the electrical system is reduced, the faster the turbine operates. By turning the switch in the vehicle, the resistance is thus reduced.

Toyota Supra Mkiv: usual ventilation problems

Dirty air ducts

If the ventilation ever turns but very little air arrives in the interior of your Toyota Supra Mkiv, it is plausible that the air shutters are blocked. Using a screwdriver flat, you can remove the air flap valves. You just have to look inside if they are clogged. If ever it is the case you can dust them, as well as the valves.

Dirty cabin filter

If you see odors and the ventilation lacks intensity, the malfunction probably comes from the cabin filter of your Toyota Supra Mkiv. It becomes blocked and piled up bacteria as time goes by. It remains totally common that it is dirty, it serves to clarify the air that reaches us. There is no manufacturer's instruction as to when to replace it. We advise you stupidly to remove it, look at its condition. If it is particularly dirty, it is best to replace it.

Resistance of the blower HS

If ever the ventilation buttons on your Toyota Supra Mkiv do not work well, if at all, it is probably due to the resistance. The resistance increases the voltage to increase the speed of this turbine. Strange ventilation may be due to resistance malfunction. This little electronic chip is complicated to repair. You will have to replace it.

HS blower motor

There are two rather regular malfunctions concerning the blower. The brushes may be damaged. The more time passes, they will be able to deteriorate and produce false contact. Your fan may spin very randomly, or may not work at all. It also happens that the dysfunction comes from bearings of the fan motor. If the ventilation makes a sharp noise, comparable to a rusty mechanism, it happens that its bearings require lubrication. We invite you to comment on this post when your dysfunction is different in order to help other readers. Enjoy the road!
