What is a blower motor?

The blower motor is the fan that pushes heated or cooled air through dashboard vents based on the climate system settings and the fan speed selected.A blower motor is the component within a home’s HVAC system. The motor blows heated air through vents when the heating system is in use. Conversely, some blower motors blow cold air when the air conditioning system is in use.

What is the purpose of a blower motor?

The blower motor turns the blower fan, sending the air through your air ducts and into each room of the home. If your blower motor is single-speed, it will operate at 100% speed until the thermostat indicates that the desired temperature has been reached.

Does the blower motor control heat?

The blower motor is an important part of your vehicle's heat and air conditioning systems. Without it, you can't control the temperature of your cabin — not a dire consequence, but definitely a major annoyance in extreme heat or cold.

How does a blower work?

Air enters the centre of the impellers, and then is divided between the impeller blades. This increases the volume of the air stream, and increases the speed of the air using centrifugal force. The high-velocity air that is accelerated as a result is then contained in the blower housing, creating pressure.

Can you drive with a bad blower motor?

Should you drive with a bad heater blower motor? A bad heater blower motor will not affect the safety of your car, with the possible exception of you not being able to clear the windshield of snow, ice, or condensation if the defrosters don't work.
