Power to the blower motor is fed through the blower motor resistor, so if it fails or has any issues power can be cut off to the motor. A blower motor without power will not be able to produce any air pressure, and as a result the heating and air conditioning system will be left with no air coming from the vents.

What would cause an AC unit to not turn on?
Several thermostat issues can cause your air conditioner not to turn on. One of the most common problems is disconnected or lose wires. If the wires are frayed, not connected, or dirty, your air conditioner will not be able to turn on. Another common problem is a faulty thermostat.
Why is my AC not coming on?
Check your breaker box for a blown breaker or tripped fuse. You may be able to fix this AC issue with the flip of a switch. If that doesn't do the trick, check the wiring in your thermostat. A loose or frayed wire could also prevent your unit from turning on.
Does heater core affect AC?
Does a bad heater core affect air conditioning? In most cases, the answer is no. The heater relies on hot engine coolant, whereas the air conditioning (A/C) system uses refrigerant. The heater and A/C are, for the most part, two separate systems.
How long should an AC blower motor last?
The average lifespan of an AC fan motor is about 12 years. An AC fan motor can last more than 12 years if it's kept clean and cooled as needed. On the other hand, without annual maintenance checkups, your fan motor may only survive between one and three years.
What causes blower motor failure?

Is there a fuse for blower motor?
How do you test an AC blower motor resistor?
Place one lead of the Ohmmeter on terminal 1 of the resistor. Place the other lead on terminal 2 and check against specifications. If this circuit is open, showing infinity on the Ohmmeter, the blower resistor must be replaced. Move the lead from terminal 2 to terminal 3 and check this reading against specifications.

How do I know if my air conditioner blower is bad?
Inspect your air filters. Lots of times, airflow restriction from a dirty filter will cause a blower motor to overheat. The excess heat in the motor will cause its performance to degrade, and the motor may fail altogether. If your blower has a fan belt, take a loot at it. If the belt is snapped, then the blower won’t work.
