I have read all the articles in regards to the elimination of heater, relay and resistor block problems...i have installed a new resistor, a new blower relay as well as a new resistor and pigtail...all to no avail.. i have even installed a new heater/ac bezel with new knobs...i am at my wits ends..please advise what's next..could it be the dreaded blower motor?
