3-Speed HVAC Fan Blower Motor Resistor For Datsun Nissan 720 Pickup
27150-03W20 can replace 27150-03W10
PLEASE READ THIS CAUTION BEFORE YOU BUY THIS
These resistors have an onboard fuse
The original ones were two strips of copper with a solder blob holding them together
If your resistor fuse is blown, there are two things that you must check and correct so that you do not blow the fuse on your new resistor
1) Bad or dying blower motor- make sure your blower motor spins freely and runs at full speed when tested with 12 volts
2) Because the resistor generates heat during operation, it is installed such that air blows across it
Low air flow from either a bad blower motor, or an obstruction such as leaves, paper, animal nest, a rag, etc will cause the resistor to overheat and melt the fuse
So if the fuse on the resistor blows, it is not because the resistor is defective, it is because something blew the fuse
Another problem with the earlier fuse design, is that it used a ceramic screw to hold everything together
These ceramic screws were prone to break, which causes all of the fuse parts to fall off and get lost, resulting in an open circuit
You will notice that the new resistor uses a metal screw so that this can not happen
