What happens if blower motor fails?

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.A blower motor that does not operate at all is one of the first signs of an issue with the blower motor relay. Because the relay is the switch that supplies the blower motor with current, if it fails internally, power will be cut off from the circuit of the blower motor. This means the motor will no longer run or blow any air out of the vents.

Can you drive with a broken blower motor?

What are the symptoms of a bad blower motor resistor?

1. Blower motor stuck on one speed A common symptom of a faulty blower motor resistor is a blower motor that is stuck on one setting. The blower motor resistor is the component directly responsible for controlling the blower motor fan speed. If the resistor shorts or fails, it may cause the blower motor to remain stuck on one fan speed.

What causes a blower motor fuse to blow?

If the blower motor relay develops any sort of problem that hinders its ability to properly limit and distribute power, it may cause the blower motor fuse to blow. Any sort of electrical spikes or excessive current from a bad relay will blow the fuse and cut power in order to protect the system.
