Where is the blower motor resistor on a Mazda 5?
In many cars it’s fairly easy; the blower motor is located behind the glove box and held by 3-4 screws. In others it might be located inside the dash (e;g Mazda 5) which makes replacement difficult. If you need a proper diagnostic procedure, we posted several links where you can access a service manual for your car for a subscription fee.
How much does it cost to replace a blower motor resistor?
The blower motor resistor or control module replacement is not very expensive. For example, one of our colleagues had a problem with his 2011 Ford Escape: the fan only worked at the speed 4. He paid $50 to diagnose and $112 to replace the resistor at a local Ford dealership.

Where is the blower motor on a Ford E250?
On the Ford E250, it’s located on the passenger’s side right behind the battery. The most common problem here is having a blower motor that doesn’t work at all. Other times, you may notice that it doesn’t work at certain speeds. This is mostly caused by a bad resistor.
The Ford blower motor resistor assembly, covered by this tutorial, has 3 different resistors in series. The purpose of these resistors is to reduce the amount of the blower motor’s current that’s passing through them (as you’re probably already aware, these resistors are located between the blower motor and ground).
How many resistors does a blower motor switch bypass?
Current passes thru’ only 2 resistors. Current passes thru’ only 1 resistor. The one blower motor speed that doesn’t depend on the blower motor resistor assembly is HI since the blower motor switch accomplishes this speed by completely bypassing the blower motor resistor assembly.
What is the ignition system wiring diagram for a 1993 Ford F150?

What does the resistor on a heater do?
It is responsible for controlling the blower motor’s fan speed. When fan speed is changed via the knob on the instrument cluster, the blower motor resistor changes setting, which changes the speed of the blower motor.
What does it mean if your blower motor is not working?
Average rating from 849 customers who received a AC is not working Inspection. The blower motor resistor is an electrical component that is a part of the vehicle’s heating and air conditioning system. It is responsible for controlling the blower motor’s fan speed.

Where do I replace the resistor on my blower motor?
To repair the problem, simply replace the resistor block. It’s usually located in the ductwork (to keep the coils cool) below the glove box. Unplug the electrical connector, remove the screws and replace the unit. Replacement blower motor resistor blocks are usually available from any auto parts store or the dealer.

What happens when a blower motor resistor gets too hot?
If the fan malfunctions (like if the fan shaft is spinning in the blower cage hub without spinning the cage) so that no air is moving past the resistor but current is still creating heat in the resistor pack, the thermal fuse that is integral to the resistor assembly opens the electrical circuit to prevent the resistor (s) from getting too hot.
Can a broken motor switch stop a blower?
A broken blower motor switch can also stop the blower from changing to certain speed settings. If your blower motor cannot change to certain speeds, check both the resistor and the switch on your dashboard. The most common failure points are the resistor and the motor itself.
What is the role of the blower motor switch?
Now to be a bit more specific, to achieve LO or M1 or M2 blower motor speeds… the blower motor switch is the component responsible for rerouting the blower motor’s current through a specific combination of these resistors (within the blower motor resistor assembly). Here’s the breakdown: Current passes thru’ all 3 resistors.
How to test the blower motor resistor thermal fuse?
Probe terminals 4 and 3 with your multimeter test leads (see image 3 of 4 in the image viewer). Your multimeter should register a resistance of about 0.2 to 0.3 Ohms ( Ω ). This test also test the continuity of the blower resistor thermal fuse.
Why is my Ford Focus fan not working?
Some condensation from the A/C, or just incoming moisture, had slightly corroded the bearing for the fan motor so it wasn’t turning as smoothly as it should. (In some cases I have heard of them squealing). As the airflow from the fan is used to cool the resistor pack eventually the pack gets too hot and blows the thermal fuse.
What are common reasons my Ford Focus has air conditioning problems?

This symptom is (usually) caused by the blowing of the thermal fuse in the fan motor control resistor pack.
What causes a fuse to blow on a blower motor?
If the blower motor relay develops any sort of problem that hinders its ability to properly limit and distribute power, it may cause the blower motor fuse to blow. Any sort of electrical spikes or excessive current from a bad relay will blow the fuse and cut power in order to protect the system.
What happens if you have a bad blower motor?
The blower motor is the component responsible for pushing air through the vents of your vehicle’s heating and air conditioning systems. Without it, the AC system will not be able to circulate any heated or cooled air.
