Hi,
I am trying to make the blower/ heater fan turn on. I am getting battery voltage all the time at the plug in the engine bay that connects to the motor no matter what position the fan speed switch is in. I assume the fan speed switch sets the resistance in the circuit and when its in the off position I should get 0V at the plug? I found a wiring diagram but I have 4 wires (one is 3 pin connector and the other is a single pin connector)going to the heater resistor not 3 as shown in this diagram? I`m confused, a correct wiring diagram would be very helpful for me if I have the wrong one.
My blower motor does not turn on so I am guessing there is high resistance somewhere in my circuit
