What’s The Function Of A Blower Motor Resistor? These sporadic issues indicate trouble with the blower motor resistor or some form of electrical malfunction. Therefore, you may be getting high air pressure one minute and it cuts out a minute later. Yet, there’s also the possibility that the system is going to malfunction sporadically. We’ve already discussed how you may only be able to get one setting to work or a particular speed to work. You want to be sure you are replacing the right part so the problem doesn’t continue. It may be that the blower motor itself has gone out. It’s important to note that this problem requires a professional diagnosis. Yes, you can roll the windows down, but that’s not always convenient, especially if it’s raining outside. Without air pressure coming out of the vents, you are going to be uncomfortably hot or cold in extreme weather conditions. Power gets supplied to the blower motor through the resistor, so any short or malfunction can cut off the power. With a faulty blower motor resistor, this problem is possible at any time. One of the worst possibilities is when the air stops blowing out of the vents. Therefore, a proper diagnosis is needed before you replace any parts. However, other problems can cause the same trouble, such as a defective blower motor switch. As an example, you may be able to use the lower fan speed settings but not the higher ones or vice versa. When the internal components fail or a short occurs, you are going to notice these malfunctions when attempting to change the settings. If you attempt to change the airflow settings and some don’t work, the blower motor resistor could be causing trouble. You may still be able to get the heat or air you want, but you won’t be able to adjust the speed. So, when it fails or shorts, the motor can become stuck. The blower motor resistor is in charge of controlling the speed that the blower motor fan operates at. If you can’t get the motor off of a high or low setting, the resistor could be the problem. Yet, one of the most common symptoms of a defective blower motor resistor is when the motor gets stuck on one setting. You should be able to easily choose the setting you want the fan on. Most of today’s heater and air conditioning systems come with multiple fan speed settings. Furthermore, it can cause an inconsistent or intermittent fan speed, leaving you without proper airflow.ĭive into these symptoms with us. The various airflow settings may also fail to work or you may not get any air from the vents. When the blower motor resistor goes bad, the motor can get stuck at one speed.
