Why does my blower motor make a squeaking noise?
This may be a sign of a faulty blower motor. As you might know, these have electric motors in them that wear out over time and will begin to make squeaking or grinding noises as the bearings begin to wear out. The electrical contacts may also wear out causing the motor to fail.
Why does my a / C make a loud roaring noise?
The only tricky thing that might make it take longer to clean out is the blower motor’s proximity to the passenger airbag, so for that reason, I leave this type of thing to a professional.

Why does my car fan not turn when I turn it off?
When one or both bushings are worn out, applying power on the motor will pull the armature to one side and cling to the core winding instead of making the armature turn. When the fan is “off”, there is no magnetic field on the core so the armature is loose so you can easily turn it.

If you experience low air flow from your blower motor the most common thing that goes out is the blower motor resistor. If you have faulty blower motor resistor you may experience low air flow and the heater ac fan not blowing hard.
Why is my air conditioner fan not spinning?
It takes much more energy to get the outdoor fan going than it does to keep it running. It needs that extra boost from a start capacitor. So, if the capacitor attached to your fan motor is bad, the fan won’t start spinning. Here’s an easy way to test if the fan’s capacitor is bad.
Can a bad capacitor cause a fan not to start?
You took over its job of kick-starting the fan by pushing the blades. If the fan doesn’t start running, you may have a bad fan motor. If you have difficulty getting the blades to turn, there may be debris wrapped around the fan axle, or the motor bearings may be dirty or jammed. Here’s a second way to check for a bad capacitor.
