What is your question?
my heater will not change the degree of heat. if you are driving over 40 it will blow hott air. So we have tried changing the heater control board, heater resister, we know the fan blows we have taken it out and tried it seprately. we are thinking that it might not be getting power... we are just unsure... can anyone help!
