Hi, i am a v70 d5 2002 driver that just joined. I have just removed my 9441233 headlight switch because it appeared dead in the sense that none of the indicator lights were functional, and none of the functions of the panel worked at all anymore. That includes headlight adjustment, and dashboard lighting adjustment. Anyway, i found a replacement for a nice price (70 euro) but i can't tell whether the thing itself is broken, or something in the wiring going to it. is there any way to tell, or should i just replace ? Thanks!
