REPLACE THE PIGTAIL AS WELL, THOSE WIRES AND PLUG HAVE BEEN OVERHEATED FOR SO LONG THAT THEIR RESISTANCE IS LOW ALLOWING STILL HIGH CURRENTS.So a few months ago, my heat started only blowing on high. I did my research and replaced the blower motor resistor. It fixed the problem, about two months later, it happened again, and I replaced it again. After about a week it’s now gone out again? What else could it be besides the resistor?
THE PIGTAIL IS AVAILABLE FROM AMAZON FOR A FEW BUCKS. JUST MAKE SURE THE CONNECTORS ARE THE BEST POSSIBLE!!!! LOSE CONNECTIONS CREATE HIGH HEAT.
I HAD THE SAME ISSUES X 3 TILL I REPLACED THE PIGTAIL. STILL NO MORE PROBLEMS 4 YEARS LATER.
