Ok so I am experiencing some intermittent fan issues with my heater and with pretty constant 0-20 degree weather that is no good. So I was looking around and saw issues with blower motor control modules and blower motor resistors. Can anyone tell me which issue I am having so i can order the right part? I do have the automatic hvac controls and even if I turn on the manual control the fan does not respond but it will come on just not at any certain time. Thanks for the help!
