    2002 Wrx Heater Blower Fan not working on any setting 1-4

    I have read through countless threads on Heater Blower Fans and resistors and i feel like i have a pretty good understanding of how it all works. My major question is when i turn my knob to 1 2 3 or 4 nothing happens and ALSO if the A/C Button is depressed it never lights up green like it is should. I already went and purchased a used fan transistor setup and i am ready to swap them out but my worry is my problem lies in the blower motor relay tucked up behind the fuse panel to the left of the steering wheel. Is the fact that the Green light on the A/C button not lighting up a tell tale sign that it is that relay and not the actual blower motor?

    If the light doesn't light up, I'd think that the control panel itself isn't getting power. So that could be a fuse, relay, or the panel itself. With that, I don't think it'd be the blower motor.

    Before doing anything more laborious, make sure the heater switch didn't die on you and even easier check the fuses
