Is Blower Motor Replacement a DIY Job?

We are all looking for ways to save money, and that includes spending less on car repairs. Your car’s heater contains a blower mower and resistors that may fail, in which case you will lose the ability to control fan speed and temperature. Fortunately, with the right tools and extra time, a car’s blower motor is simple to replace in New Palestine, IN. Here is how to replace a car’s blower motor:

  • Clear a space: You need room to work and safer conditions. Start by disconnecting the negative battery terminal so you do not have a shocking experience. Place the terminal where it will not touch metal. Remove the passenger-side floor mat for ease and find the cover to your dashboard controls under the glove box. Remove the screws and open this cover. If your vehicle has a footwell light or lights in the door, be careful not to damage them.
  • Remove the old blower motor: The blower motor is attached to the climate control unit with screws. You will likely see it just below your heater and air conditioning vents. Carefully remove the screw and then the motor—these parts are fragile, so take your time and move slowly. When you remove the motor from the housing, look out for a plastic wheel, usually on the far side of the motor housing. Do your best to avoid dropping pieces in the dashboard or you will suffer loud vibration noises as you drive.
  • Change out the plastic wheel: Remove the old plastic wheel and replace it with the new one. If there is a spring clip holding it in place, be careful not to break or lose it. Replacements are hard to come by if that happens, and you will likely need to special order it from a dealer. Lock the wheel into place and put the motor back into the climate control system. Make sure it’s secure and that you reconnect all the wires under the dashboard.
  • Test: Before you reattach the dashboard cover, reconnect the negative battery terminal. Start your car and run the heater and air conditioning. Check temperature and fan speed; it should respond to the dials for your climate control system. Once you confirm that the blower motor works, replace the dashboard cover and floor mat. If you find your blower motor still does not work, it is likely time to make a car repair appointment. Your issue with heating and cooling may be something other than the blower motor.
