Hyundai Santa Fe Blower Not Working – How To Fix

Hyundai is one of the largest car manufacturers in the world. The Hyundai Santa Fe is one of the popular and competitive SUV cars. However, there are some common problems that are related to the SUV, such as the blower not working. A blower that does not work can be very troublesome for any car owner because it prevents air circulation in your vehicle and makes it more difficult to stay cool inside.

An extremely struggling blower motor is very likely to have internal components that are worn out. This puts a lot of strain on the resistor when it is operating, causing it to overheat and burnout. Therefore, in Santa Fe models it is generally recommended that the old blower motor should be replaced, as well as the resistor that will be replaced. Here’s what you can do:

Check for a faulty control module

The role of the blower motor resistor is to regulate the speed of the blower motor. When you increase or decrease the speed of the AC fan in your Santa Fe, the climate control unit sends a signal to the resistor module that indicates if the flow of electric current to the blower motor should increase or decrease. If the resistor module develops a fault, it is possible that the blower motor will stop working.

Check for a bad relay

Relays are also called electromagnetic switches. They are used to switch electrical loads on and off. It is possible that a bad relay is also the cause of AC blower motor failure in your Hyundai Santa Fe.

Find out where the blower motor relay is located in the Santa Fe model that you are interested in. This information is also written in the owner’s manual of your vehicle. If you are lucky, you will be given a wiring diagram and it will be drawn on the facing. You can test it by switching it out with other relays in the fuse box that have similar amp ratings. Before you replace the battery on your vehicle, it is a good idea to disconnect the battery from the vehicle.

Check for a blown fuse

Fuses are like circuit breakers that protect the electronics in your car. If a fuse blows, it will not be able to provide the proper current to power the blower motor resistor. It is therefore recommended that you check all of your fuses and replace any that have blown out.

When you check the fuse, pull it out of the fuse box with a fuse puller or needle nose pliers, and hold it in front of the light. If the metal strip is broken in the middle, that means that a fuse has blown. You must replace the part with one that has the same amount of amps and subsequently the same color.

Check for a broken fan belt

The purpose of the fan belt is to transfer mechanical energy from the engine to the blower motor pulley and vice versa. If it breaks, it will prevent air circulation in your vehicle and make it difficult to stay cool inside. When replacing this part, you should also take care of ensuring that there are no loose or damaged parts when installing it back into place on your Santa Fe model that you are interested in.
