My Heater is not working. I have replaced the blower motor resistor. The wiring harness to the heater components. I have checked the relay, it’s ok. Also made sure ground was good. I have also manually tested motor to make sure it works. It’s good. What else could it be?


Which signal is missing at the blower motor, power or ground?
