My Car A/C Was Working on Only the Highest Setting and Now It's Not Blowing Any Air - Is It the Blower Motor or the Blower's Motor Resistor?
When your car's air conditioning system stops blowing air, it can be frustrating and uncomfortable, especially during hot weather. If you've checked the fuse and relay and they're both good, then the next step is to troubleshoot the blower motor and the blower's motor resistor.
The blower motor is responsible for circulating air through the AC system. If the blower motor is not working, then no air will be blown through the vents. The blower's motor resistor is responsible for controlling the speed of the blower motor. If the resistor is not working, then the blower motor may only work on the highest setting or not at all.
To test the blower motor, turn the ignition to the "on" position and set the AC to the highest fan setting. Then, listen for the sound of the blower motor running. If you don't hear the blower motor running, then it may be faulty.
To test the blower's motor resistor, set the AC to a lower fan setting and listen for the sound of the blower motor changing speed. If the blower motor does not change speed, then the resistor may be faulty.
Replacing a blower motor or blower's motor resistor is a relatively simple repair that can be done at home. However, it is important to consult your vehicle's repair manual before attempting any repairs.
