Where is the heater blower resistor located?
The heater blower motor resistor is often found beneath the dashboard. It is located in the heater and air conditioning compartment. It’s connected to the air conditioning system, where it can adjust the speed of the blower motor fan. It can also be found behind the glove box of some vehicles.
Where is the blower motor resistor located on a 2014 Ford Focus?
The blower motor resistor is on the driver side of the HVAC unit. You’ll have to remove the accelerator pedal to gain access to it. That’s the only step the Ford manual says.
Where is the blower motor resistor module located?
It’s located inside the dash, often on the opposite side of the steering wheel or inside the engine compartment on the firewall. A blower motor resistor or a blower motor control module is the part that controls the speed of the blower motor.
How do I know if I need to replace the blower motor or the resistor?
Symptoms of a bad heater blower motor resistor
- Fan does not work at all, so no air comes out of the vents.
- Fan only works on some speeds and not others.
- Fan only works on the highest speed.
- Fan runs all the time and can’t be controlled with the fan switch.
- You see smoke coming out of the vents.
What happens when blower resistor goes bad?
If the resistor shorts or fails, it may cause the blower motor to remain stuck on one fan speed. The heating and air conditioning systems may still function at one speed, however the resistor will have to be replaced in order for full functionality to be restored.
What are the symptoms of a bad blower motor relay?
Blower motor does not function. One of the first symptoms of a problem with the blower motor relay is a blower motor that does not function at all.
How do I know if it’s the blower motor or the resistor?
Typically, if the fan will work on some speeds but not on others, the resistor is suspect. Okay, let’s say there’s no melting going on, but your fan doesn’t work on all speeds. Typically, if the fan will work on some speeds but not on others, the resistor is suspect.
How do I know if I have a bad blower motor resistor?
If you try to increase the air pressure and you feel no difference in the pressure blowing, then your blower motor resistor may be failing. A damaged blower motor resistor will work on one fan speed which may not be enough to keep the inside of your car cool or warm enough.
