Do not confuse the air conditioning , heating and ventilation of the Toyota Supra Mkiii. Heating and air conditioning are systems that offer the possibility of lowering or increasing the temperature. The first through the heat generated from the engine, and the other with a liquid refrigerant . Ventilation is all the circuits and systems that will allow air to reach the interior. The essential element is the kicker which propels the air within your vehicle. If there is little or no air supply, this is probably a ventilation problem. This guide will show you how ventilation works, so that you can better spot problems and understand how to fix them.
How a ventilation works on a Toyota Supra Mkiii
Ventilation is primarily used to regenerate the air inside the interior of the Toyota Supra Mkiii. As for the pulser, it usually consists of a resistor, a turbine, and a motor. The lower the integral resistance of the electrical system, the faster the turbine operates. By turning the button in the passenger compartment, the resistance is lowered.
Toyota Supra Mkiii: usual ventilation problems
Dirty air ducts
If ventilation does work but little air enters the interior of the Toyota Supra Mkiii, it is likely that the air shutters are clogged. Thanks to a screwdriver flat, do not hesitate to dismantle the air flap valves. Just look in there if they are crowded. If ever, do not hesitate to scour them, as well as the valves.
Dirty cabin filter
If you can smell odors and ventilation is poor, the problem is most likely the Toyota Supra Mkiii cabin filter. This clogs and accumulates bacteria with time. It is quite normal that it is dirty, it is there to filter the air that reaches us. There is no manufacturer's recommendation as to when to replace it. We simply advise you to remove it, check its condition. If it is really dirty, it will be better to replace it.
Resistance of the blower HS
If ever the ventilation buttons of the Toyota Supra Mkiii work poorly, if at all, it is certainly linked to the resistance. This resistance allows to increase the voltage to be able to increase the speed of this turbine. A lackluster operation of the ventilation may be due to a resistance problem. This microchip is difficult to troubleshoot. You will have to replace it.
HS blower motor
There are several fairly regular problems with the kicker. The brushes are worn. Over time, these will be able to be damaged and generate electrical faults. The fan may spin randomly or even not operate at all. It is also possible that the problem comes from bearings of the fan motor. If the ventilation makes a high-pitched noise, such as rusty mechanics, the bearings may lack lubrication. We invite you to comment on this guide if your problem is different to help other readers.
