What tools are needed to replace a car AC blower motor?
To change the AC blower motor in your car, you'll need a few tools.
Get a screwdriver set with both flathead and Phillips heads for taking out screws. Use a ratchet and socket set to loosen bolts that hold the motor. You might need an extension bar to reach bolts that are hard to get to.
A trim removal tool helps you take off panels without scratching them. An inspection mirror lets you see areas that are out of sight, while a flashlight helps light up dark places.

What are the signs of a failing car AC blower motor?
If your car's AC blower motor is having issues, you might notice a few things.
First, you could feel less air coming out of the vents, even if the fan is on high. This might mean the motor isn't working well to move the air.
You could also hear strange noises, like rattling or grinding, from where the blower motor is. This noise can mean parts inside are worn out or broken.
Sometimes, the blower motor might work only sometimes. This stop-and-start behavior could be due to electrical problems or the motor failing.
If you can't change the fan speed, the problem might be with the blower motor resistor or the motor itself.
Lastly, if you smell bad odors from the vents, it could be because the blower motor is overheating or not working right.
