Check the Fuses, Relays, and Electrical Connections This is often the case. Your vehicle should have a complete relay diagram showing the location of all of the vehicle's electrical components such as fuses and relays. To fix any blower, the first things to look at are the fuses, relays, and electrical connections.If your blower motor is dirty or has a bad capacitor, you can call in an HVAC technician to fix the problem. On the other hand, if your motor is reaching the end of its service life, start looking for a replacement motor. It’s important to note that weak airflow can also result from dirty or leaky ducts or a clogged filter.
What causes a car blower motor to stop working?
In most cases, a blower motor resistor fails due to corrosion or overheating. Sometimes, the mechanical resistance to the motor rotation causes an excessive electric current that can overheat and prematurely damage the blower motor resistor.
Why has my blower stopped working?
If little air is coming through the vents (hot or cold), then it could be because the blower motor for the fan or a switch or resistor that controls fan speed isn't working. Another cause might be that the electronically controlled “blend doors” that direct air flow are stuck or broken.

How do you tell if it's the blower motor or resistor is bad?
Signs of a Bad Blower Motor Resistor Loss of HVAC fan control (total or certain speeds) The fan only works on its highest speed setting. No air coming from vents. Intermittent or inconsistent fan speed.
How do you know if your car blower motor is bad?
You might also hear ongoing whirring noises, or noises that change or get louder if you increase the fan speed. These are all signs of problems with the blower motor. In some cases, you may even notice smoke or smells of burning while driving, in which case you should pull over immediately.
Is there a fuse for the blower motor?
What causes a car blower motor to stop working?
In most cases, a blower motor resistor fails due to corrosion or overheating. Sometimes, the mechanical resistance to the motor rotation causes an excessive electric current that can overheat and prematurely damage the blower motor resistor.
How do I know if it's my blower motor or 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.
Is it hard to replace a blower motor?
The replacement of the blower motor is common and straightforward, so most shops will perform the repair — many on the same day.
Where is a blower motor located?
The blower motor is usually under the dashboard on the passenger side. Blower motors that make loud squeaks or rattling noises may be worn out and on the verge of packing it in, but sometimes those noises are caused by leaves or other debris that can be cleaned out after the motor is removed from the vehicle.
Why is my blower not working on my AC unit?
In air conditioning mode, check the indoor unit for ice around the evaporator coil and refrigerant lines. If the fan is not working, the coil could freeze. With a frozen coil, air will not pass through until the ice melts. You should shut off the air conditioning immediately.
How many blower motors are in a car?
The number of blower motors in your vehicle depends on its climate control system. Some cars have one blower motor, but that may not be the case for some SUVs and vans. They may have two motors, one in the heater box and another in the vehicle's rear area.
Where is the blower motor relay fuse located?
Under the instrument panel, look under the glove box. On the right side of the fender wall you will find another fuse box. The blower motor fuse is easy to replace.
What relay controls the blower motor?
The blower motor relay controls the current used to power the blower motor, and is subject to the constant on and off switching.
Are blower motors expensive?
Cost to Replace Central or Forced Air Blower Motor Replacing a blower motor costs $450 on average with a typical range of $250 to $800. With a warranty, you might pay as little as $150 for labor alone. For high-end models, like those with large motors or access issues, you might pay as much as $2,000.
How much does a blower cost?

What happens when the blower motor on a car goes bad?
A bad blower motor will sometimes overheat, causing a “hot” smell to come out of your air vents. In the worst scenarios, your blower motor may actually start to burn. Yikes! What causes a bad blower motor?
Why is my AC fan blower motor not working?
The most common causes for AC fan blower motor not working are blown fuse, bad relay, resistor or control module malfunction and faulty blower motor. However, a bad electrical connector or broken wire, or a defect in the climate control unit can also cause the blower motor to stop working.
What should I do if my blower motor won’t start up?
Replacing the belt is a fairly simple fix. Another thing to check is the capacitor. The capacitor is used to start the fan so it’s worth checking if your blower motor won’t start up. Check out this video from AC Service Tech that shows you how to check a blower motor’s capacitor and windings:
