Is there a fuse for the heater blower?

The blower motor is powered by a fuse-like device called a relay. If your heater or air conditioner does not blow air through the vents, this could indicate that the blower motor fuse has probably blown. While replacement is easy, the exact location of your blower motor fuse may vary from vehicle to vehicle.

What can cause a 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.

Where is the fuse for the heater blower motor?

Many vehicles have two fuses for the blower motor, one in the interior fuse block and the other under the hood. The blower motor is usually under the dashboard on the passenger side.

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. Over time, it can eventually wear out.

Where is the blower motor switch?

The blower motor is the electrical switch on the interior of a vehicle that allows the driver to control the vehicle's heating and air conditioning system. It is usually built into the the same control panel that houses all of the AC system controls, and is labeled with numbers and symbols to indicate blower fan speed.

Where is the blower motor reset button?

Locate the reset button on the furnace and press it to reset the furnace. It is usually located inside the blower compartment on the side of the blower motor. Be cautious as the housing may be hot. If the button is popped up, press it down.

Why will a blower run on the on position and not on auto?

Other Blower Fan Won't Run Problems

The fan will run and blow warm air but only in FAN or FAN ON mode - delivering heat - but NOT in AUTO mode. This is a bad temperature sensor in the unit; replace the fan limit controller.

Where is the blower motor relay located?

The blower motor relay is generally located in the under-hood fuse box or in the under-dash fuse box. A blown fuse can mimic relay failure.

Is there a fuse for the blower motor resistor?

A fuse is often located on the resistor board. The fuse only protects the low and medium blower speeds. High speed will still work if the resistor fuse is blown.

Can a blown fuse cause heater not to work?

Fuses. A blown fuse is a symptom not a cause. ... Always use a replacement fuse with the same amp rating as the original. If a new fuse blows as soon as the blower is turned on, the heater circuit or motor may have a short that should be investigated.

How do you check a blower motor fuse?

Use voltmeter or ohmmeter to check for a blown fuse. If you find one, replace it. Start car and see if blower motor works. If fuse blows again, check for loose circuits.
