A/C Blower Motor Installation Made Easy

If there's no air coming out of the air conditioner, something must be wrong with the A/C blower motor. This device is used to de-ice or de-fog the windshield and cool the cabin of the car. This way, it will give the optimum comfort that you and your passengers deserve. If yours is busted and you want to install a new one, you can definitely do so yourself. All you need are some tools and this guide to help you out.

Required skill level: Novice

List of tools that you'll need:

  • Wire brush
  • Screwdriver
  • Socket wrenches
  • Pliers
  • Doing the disconnection

    Before working on the vehicle, make sure that you separate the cable that's linked to the negative battery terminal. Use a socket wrench to do so. Disconnecting this will give you a chance to clean the negative terminal post, as well as the battery cable end; make sure you use the wire brush to clean them. After, separate the wiring harness or any wires from beneath the blower motor. Take note that the back faces the front side of the engine compartment.

    Removing the previous A/C blower motor

    Locate the blower motor screws that secure the A/C blower motor inside the heater case. Take note that the screws are not visible and you need to feel the screw heads to locate them. Take out the blower motor from the heater case and remove the blower wheel from the motor shaft. This can be achieved by squeezing the clamp. With this technique, the blower wheel can easily be taken out of the shaft.

    Installing a new A/C blower motor

    Set up the blower wheel on the new brand new motor shaft. Make sure to place the blower motor with the screws that you removed from the previous step. Attach the wires to the blower motor and place the negative battery right back in. And with that, your job is complete!

    • AC Delco vs. 4-Seasons A/C Blower Motor: Which One Will Get the Final Blow?

      The A/C blower motor is the one in charge of moving air to the evaporator, out of the air ducts and into the cabin. If you're looking for a quality one, AC Delco and 4-Seasons are two of the top-selling brands in the market today. But, you can only choose one when it comes to making the final decision. If you're not sure which one to get, then here's a guide to help you out.

      Product choices

      These two brands are known to produce high-quality blower motors. But when it comes to choices, 4-Seasons has 31 product options to choose from compared to the 7 types that AC Delco offers. That's a lot more product range compared to the latter.

      WINNER: 4-Seasons

      Matter of performance

      While the 4-Seasons A/C blower motor is crafted to operate just like the original part, since it's made to exceed the OE specifications, AC Delco is equipped with permanently lubricated and self-aligning bearings to improve and provide optimum performance. Also, it's made to last longer than any other brands.

      WINNER: AC Delco

      Price matters

      Some people believe that the more expensive a product is, the more it's made to be durable and tougher than any other brands in the market. The 4-Seasons A/C blower motor is priced at $15.68, whereas the AC Delco blower motor at $27.25. It all depends on you which you're going to choose since both are manufactured from top-grade materials. But when it comes to affordability, the answer is definitely obvious.

      WINNER: 4-Seasons


      When looking for a product, warranty is very important in case there's a need for you to return a defected part to have it switched with a new one. The 4-Seasons A/C blower motor comes with a 3-month limited warranty and AC Delco with a 12-month limited warranty.

      WINNER: AC Delco

      The verdict

      These two brands are down to a tie, but it all depends on you. Both are produced to be durable and provide great performance to the ride, but each one comes in different prices and warranties. So no matter which brand you're going to choose, you'll have benefits that you won't regret.
