What Are the Signs of a Failing AC Blower Motor in Your Vehicle?

We’re still in the hot part of summer here in the Midwest, so the last thing you want when you’re out on the road is to have problems with your car AC motor going out. This will result in a very uncomfortable drive, especially if you’re on an extended road trip near New Palestine, IN.

What is a blower motor? This is the part in your air conditioning system that controls the operation of your AC system and regulates the temperature in your vehicle. The motor resistor and switch are capable in normal circumstances of operating at several different speeds to accomplish this.

The good news is you should be able to determine early on if you’re dealing with air conditioning problems. You shouldn’t have to get to the point where the motor fails entirely for you to know you need to get your vehicle’s AC system checked out.

With this in mind, here are several of the most common signs that indicate you have a failing AC blower motor in your vehicle that you should get checked out by a professional:

  • No air coming from the vents: This is perhaps the most obvious issue you can experience in your vehicle that will indicate an air conditioning motor problem. Obviously, if you’re not getting any air at all, there’s something wrong with the system, especially if it’s true for both the heater and air conditioning. If the motor either burns out or short circuits, it will not function at all, which means you won’t get any hot or cold air. In most cases, the mechanic servicing your vehicle will need to replace the blower motor entirely if you are to have restored operation in the system.
  • Weaker airflow than usual: In some cases, you might have air coming out of the vents, but at a much lower, weaker level than you’re accustomed to. This is one of the first symptoms people are likely to experience when their AC blower motor is going bad. It may occur when you’re either using heat or cold air. If the air is weaker, this is likely a sign that the blower motor is beginning to wear down, as a worn-out blower motor will typically not be able to provide the same level of airflow it once did. This will make it harder to regulate your interior temperatures. It will also make the blower motor want to work harder than usual to make up for it.
  • Fans operating only at some speeds: In some cases, the fan may only work at certain speeds. A reliably operating blower motor should be able to operate at many different speeds to most efficiently send air into your cabin. If it does not operate at any of its settings, then it is likely due to a faulty motor, or due to problems with the motor resistor or switch.
