I tried to find information about power transistor, since it’s quite fast moving item to USA. But I failed to search the function of this kind of transistor. Google showed me a lot of other transistors. If you know correct key ward to check this out, please comment me.
By the way, I found only below image to understand where the location of power transistor.






I don’t know if you’ve already found the answer or not but in the US it is called “blower motor resistor”. It limits current through the motor to change the fan speed for the cars HVAC system.
Thank you for your helpful comment! No body replies so I didn’t know about it. All my suppliers – they only sell the parts and don’t know exactly the function. Once again thank you for your response.
