I have a gmc sierra 2007 The blower motor only works in the first 4 positions and not number 5. I have replaced the control panel and the resitor or reostat which is conected to the fan motor with brand new parts. I also noticed that the panel lights up but not the knobs. 200 dollars in parts for a partial result. What am I missing?
