My 2004 Rover 45 heating has suddenly decided to only do cold or hot and nothing in between. I suspected it’s the heater resistor. The problem is that the heater resistors I see online are nothing like what’s in my car. I think from what I could find out my one is called a “facelift”. But to replace that one is ridiculous money compared to the other ones. So my question is can I change to the normal three coil resistor instead?
