Hi all I'm hoping you are able to help me out. The fan in my 307 stopped working and through research I found that the heater resistor is most likely to blame. Removed it and found that it had melted the wires. So... Now I have a new one and just put it in. Everything seemed great but then it got very hot and started smoking. Has anyone else changed their resistor? What am I ding wrong? Any help greatly appreciated!
