One can purchase a blower motor resistor either in car part shops, like Autozone. Alternatively, one can try looking in eBay for cheaper blower motor resistors.
the switch, or the blower motor resistor, or blower motor usually it the last two at one time
The blower motor resistor is the common failure. It comes with the wires attached that plug directly to the blower motor itself. If there is another wiriing harness that is damaged then you will have to buy it too. The resistor failure has been linked as the only cause of the melted wires other than the blower motor itself. The motor can be tested with 12v power to it and it should run on high speed when tested.
the blower motor resistor is located behind the blower motor which is located behind the glove box there is clip wires you need to disconnect and then connect the new one.
One can replace blower motor resistor on 2003 Nissan altima by removing the old using spanners and replacing it with a new one.
Locate the resistor under the dash attached on the blower motor housing. Disconnect the wire harness connector. Remove the resistor and install a new one.
There is only one blower motor resistor and it is located in the evaporator housing.
If you have only high speed on the blower motor or you are missing one or more low speeds, chances are the blower motor speed resistor is burned out.
On a 1995 Ford Econoline E350, the resistor is located to the right of the blower motor in the engine compartment. It is the second plug attached to the blower motor wiring harness. It has two screws and a white connector compared to the black one for the blower motor.
A bad heater blower motor resistor would effect one or more blower speeds other than high.
the reason blower does not work on all speeds, is the fan blower motor resistor. The resistor is a 4-5 step series circuit, 1 resistor is added for each reduction in speed. If one burns out then so will all speeds below it. The "high" circuit usually has a separate fuse and bypasses the resistor altogether.
take the blower motor out you will see two plugs one for the motor and the other for the resistor two screws hold it in place looks like a motherboard price for new one is about 30.00
It's on the passenger side of the car.Behind the glovebox,you will have to take the glovebox off the dash.then you will have to lay on the floor on your back,looking upward by the firewall you will see the blower motor.look behind the blower motor you will see a wire harness conected to the blower motor.Thats the resistor,after you un hook it from the blower motor you will have to take the blower motor out.It's held in by three screws,once you have taken the blower motor out,follow the wire harness that you've taken off the blower motor.you will then see the resistor with much effort its easy to get out,it's held in with two screws,you will only take one screw out to get the resistor out.
