Can a bad blower motor cause no AC?

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.

Where is the blower motor reset button?

A defective blower motor will make a continuous sound noticeable by the passengers in the vehicle. It can manifest as a knocking, whirring, clunking, vibrating, squealing, or whining noise that persists until the blower motor is replaced.

Why do I have to hit my blower motor to work?

Blower motor only start working after i hit a bump. In most cases that is a sign of worn down blower motor brushes not making a good contact. In some cases the blower motor/resistor pigtail could cause erratic operation of the blower motor too.

Is there a fuse for the blower motor?

How do I know what size blower motor I need?

To match a furnace blower motor, you'll need to look at the make and model number of the blower motor. The details that you need to know include the horsepower, amps, voltage, speed, and shaft size of the motor.

What kind of motor is in a blower?

There are two main types of blower motors: single-speed motors and variable-speed motors. Single-speed blower motors blow air at one speed. Variable-speed motors adjust their speed to blow air at varying speed levels. A properly functioning blower motor remains a critical component of your home's HVAC system.

How much does it cost to replace a blower motor on an AC unit?

How much it costs exactly usually boils down to four main factors: The type of motor, torque, speed, and power usage, the brand, and other factors that may arise during installation. That being said, the cost to replace a blower motor usually runs between $499 and $1,875.

FAQ for the last Day

  • Do you need to change blower motor and resistor?
  • We do suggest that you replace the resistor at the same time. It may not be critical, but this will keep the system more uniform. The issue may even be related to the resistor. If you know that it is not related to the issue, then you do not have to replace it.The blower motor resistor is made of 3 or 4 small resistors that are attached to a PCB or in the form of a coiled wire. They do not get dam...

  • Can a bad blower motor resistor damage the blower motor?
  • Without any power, the motor won't run. As a result, the blower fan stays still and silent, and no air blows out of the vents. There are instances where a bad resistor will prevent the current from reaching the blower motor altogether.Will a blower motor work without the resistor? Without any power, the motor won't run. As a result, the blower fan stays still and silent, and no air blows out of th...

  • Is there a fuse for blower 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.Where is the blower fuse located? Under the instrument panel, look under the glove box. On the right side of the fender wall you will find another fuse box. The blower motor fuse is easy to replace. Does heater blower have a fuse? Many veh...

  • What happens when the heater resistor goes bad?
  • If the resistor shorts or fails, it may cause the blower motor to remain stuck on one fan speed. The heating and air conditioning systems may still function at one speed, however the resistor will have to be replaced in order for full functionality to be restored.How do I know if it's the blower motor or the resistor? Typically, if the fan will work on some speeds but not on others, the resistor i...

  • How do you know if a relay is working?
  • All you need to do is hold the relay between your fingers, there's no need to pull on it or move it. As the engine cranks over, the relay should click in one of the ignition switch positions. If that happens, then you know this relay is working properly. If it doesn't happen, then you need to proceed.How do you know if a relay is faulty? You want to feel and listen for any clicks. If you feel and...

  • How do you test a heater resistor?
  • Signs of a Bad Blower Motor Resistor Loss of HVAC fan control (total or certain speeds) The fan only works on its highest speed setting. No air coming from vents. Intermittent or inconsistent fan speed.First check, with an ohmmeter, the thermistor without any heat applied. With a PTC thermistor at room temperature or below, the thermistor should measure a very low resistance. Now apply heat, just...

  • What happens if a resistor fails?
  • When a resistor fails, it usually gets charred or burns. As a result, it either stops conducting the electrical current/signal or does not resist the current flow.When a resistor breaks down, current typically flows through the burnt resistor without any resistance and thereby passes unchecked. Other components in the circuit may become damaged from the excess current flowing through. How do you k...

  • Why would my car heater stop blowing air?
  • A car heater that's not working can be caused by the following issues: Failing or blown blower motor. Failing or blown blower motor resistor or blower motor resistor module. Bad or blown blower motor fuse, connector, or wiring.Some common causes of failure include, blocked windshield cowl drains cause rainwater to access the heater assembly, and damage the motor windings.
