Got a multi meter? Check to see if you have 12v at the plug to the motor, then check if you have ground at the plug aswell, the ground will have different resistance's depending on fan speed setting. Put the meter on continuity and it should beep if your set to fan speed 4. Unless you have a phase 3 i think they're different.
Doesnt even own a 306.
