HI
My G/F has a 2000 pathfinder with auto temp control. The blower motor just quit working the other day. I have power from the fuse / relay to the motor ( when i ground the wire from the motor the motor runs so i know the motor is good) then goes to the solid state relay ( resistor) I have the 12 volts coming into the resistor from the motor. THere is 3 wires on the reistor plug. THe ground wire on the reistor plug tests ok and is the jump the power 2 the ground it works. The 3rd wire comes from the control head. There is 9 volts comming from it but the voltage doesn't change when I adjust the fan speed. It goes to 0 when i shut the control head off. No is the control head bad or is the resistor bad ? does anyone know how 2 test it ? or had any problems ?
thanks
