m8 - it sounds like the heater resistor - ebay where i got mine from:-I own a 2002 MG ZR. Recently the blowers have stopped working on speeds 1 AND 2. 3 and 4 both work, which means they can either be completely off, or blowing at 3 or 4, but nothing in between...which you dont want just for a bit of air round the car!
Has anyone had this problem? anyone know what to do to fix it? etc
Thank you
