Purpose
The power MOS FET controls the blower motor rotation speed.
Function
The power MOS FET controls the supply voltage to the blower motor based on the gate voltage sent from the climate control unit, and adjusts the fan rotation speed (airflow volume).
Construction
The power MOS FET is installed to the A/C unit.
A transistor-type power MOS FET has been adopted and it is equipped with three electrodes, a source, a gate, and a drain.
Operation
The resistance between terminals B and A (between drain and source) changes according to the voltage (gate voltage) applied to terminal E (gate).
When the gate voltage increases, the resistance between terminals B and A decreases, allowing the current to flow easily. Therefore, the blower motor rotation speed increases.
When the gate voltage decreases, the resistance between terminals B and A increases, making current flow difficult. Therefore, the blower motor rotation speed decreases.
Fail-safe
Function not equipped.

Engine Coolant Level Inspection
WARNING:
Never remove the cooling system cap or loosen the radiator drain plug while
the engine is running, or when the engine and radiator are hot. Scalding engine
coolant and steam may shoot out and cause serious injury. It may also damage
the engine and cooling system.
