blower problem
 

hey, i got a problem with air blowing system. It doesn't blow any air, when i turn climate buttons i hear them making a noise so those work, but when i turn the button that regulates blowing speed it just turns on those green lights around the button but blower motor doesn't start. motor is working, i toke it down, powered it with battery and it worked. Fuses are all okay. any ideas why it's not working?

Maybe the thermistor (the aluminum triangular plate) that is fixed next to the motor.
