Let's not confuse the air conditioning , heating and ventilation of this Seat 128. Heating and air conditioning are systems that offer the possibility of lowering or amplifying the air temperature. The very first by means of the heat generated by the engine, and the second by means of a liquid refrigerant . The famous ventilation is all the channels and devices that allow air to get inside. The essential element is the kicker which propels the air inside your cabin. In the event that the air hardly or hardly reaches the air, this is probably a ventilation problem. We will discover in this article how ventilation works, so as to better discern the problems and understand by what means to remedy them.
How ventilation works on a Seat 128
The ventilation is primarily used to regenerate the air in the passenger compartment of this Seat 128. Regarding the blower, the latter is generally composed of a resistor, a turbine, and a motor. The lower the integral resistance of the electrical system, the faster the turbine turns. By turning the knob in the passenger compartment, the resistance is therefore lowered.
Seat 128: common ventilation problems
Dirty air ducts
In the event that the ventilation works but that very little air arrives within the passenger compartment of this Seat 128, it is conceivable that your air shutters are obstructed. With the aid of screwdriver flat, it is possible to remove the valves from the air vents. You just need to check inside if they are clogged. When this is the case, it is possible to dust them, but also the valves.
Dirty cabin filter
If you perceive effluxes and this ventilation is weak, the problem undoubtedly comes from the cabin filter of this Seat 128. The latter becomes blocked and accumulates bacteria with the years. It is completely common that it is dirty, it is used to filter the air that reaches us. There is no manufacturer's recommendation as to when to replace it. We just advise you to remove it, check its condition. In the event that the latter is particularly dirty, it will be preferable to replace it.
Resistance of the blower HS
If the ventilation controls of your Seat 128 do not work well, or even not at all, it is probably due to the resistance. The resistance increases the voltage to amplify the speed of this turbine. A strange functioning of this ventilation can be linked to a resistance problem. This microchip is complex to troubleshoot. You will have to replace it.
HS blower motor
There are two fairly common problems with the kicker. The brushes may be worn out. Over the years, these can wear out and generate electrical faults. The kicker can rotate randomly, and even not work at all. The problem may also arise from bearings of the fan motor. In the event that the ventilation produces a hissing sound, comparable to a rusty mechanism, it can happen that its bearings lack lubrication.
