Why does my blower motor fuse keep blowing?

Where is the blower fuse located?
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.
Does the blower motor control the AC?
The HVAC blower motor is the heating and cooling systems component that sends conditioned air from the furnace, heat pump, or air conditioner into the home. Once the system heats or cools the air, the blower motor forces it through the duct system and out the vents in rooms throughout the house.
What causes an AC blower to go out?
There are a number of possible reasons why this is happening, including dirt and dust buildup, bad capacitor, and an aging motor. If your blower motor is dirty or has a bad capacitor, you can call in an HVAC technician to fix the problem.
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.
What happens when blower motor relay goes bad?
If you have a faulty blower motor, you may experience low airflow from the vents, even when the fan is on high. There will be no air coming from the vents if your fan isn't working due to a bad blower motor resistor.
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.
Why will a blower run on the on position and not on auto?

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 AC relay?
The relay can be mounted on the fire wall or on the fender well. A/C control installations typically have a three-wire connection for the relay. One wire is a ground, one wire is the input from the interior control panel, and one wire is the power feed to the A/C compressor clutch.
