Nissan Xterra Blower Motor Resistor

Common Problems of the Nissan Xterra Blower Motor Resistor

The blower motor resistor of your car mainly functions as a regulator of the air temperature released by the electrically powered fan on the vehicle. It determines the air settings in your car while also making sure that the motor is only releasing the right amount of airflow. But, if your Nissan Xterra blower motor resistor is defective, it could be very difficult for you to regulate how much air should be blown during the entire time that your vehicle is running. Here are some of the most common and noticeable signs of a defective blower motor resistor:

Deceleration failure

A fully functional blower motor resistor is supposed to accelerate and decelerate the airflow in your vehicle. A defective one, however, fails to decelerate and only works at very high speed. You can easily notice this if the airflow in your vehicle seems to be working on the highest level despite the fact that it is already well ventilated inside. If this persists, there is a possibility for your air conditioning unit to also get affected and get damaged eventually. So when you notice deceleration difficulties on your blower motor resistor, have it checked or replaced immediately.

Switch problems

The blower motor resistor is controlled through a certain switch. And if this switch starts acting up, it would be difficult for you to fully control your blower motor resistor. You can notice switch problems when your blower motor does not follow the command you are willing it to do. When this happens, it would be better to take your vehicle to a mechanic and have the blower motor resistor repaired to fully enjoy its function.

Electric resistance

As with all the electrically powered parts in your vehicle, there also comes a time when your blower motor resistor defies electricity. As a result, your resistor will stop working or you won't be able to change its speed no matter how you reset the settings. This can be problematic for you because you won't be able to achieve the right airflow level for the vehicle. This can be a little difficult to notice, but once you do, make sure that you get it repaired right away.

  • How to Preserve Your Nissan Xterra Blower Motor Resistor 27 February 2013

    There are several ways on how you can possibly be able to prolong the life of your car's blower motor resistor. And, many of them do not require you to spend loads of money in the process. All you have to do is allot time for your car, and you can be able to assess damage and effectively devise ways to fix them and prevent them from happening again. Here are some of the most effective and affordable ways to take care of your Nissan Xterra blower motor resistor:


    Set a regular cleaning session.

    Every time you clean your car, make sure that you don't miss on the other parts such as the blower motor resistor. It may not be exposed to various particles or damaging conditions at all times, but it is also in need of attention and regular cleaning. Set a certain schedule for a total car cleaning session when you can spend quality minutes in getting rid of dirt from the blower motor resistor and the other parts that are often neglected. Just see to it that you are using the right tools in every procedure.


    Assess the resistor's condition from time to time.

    If you have spare money, bring your Xterra to a trusted mechanic and have the blower motor resistor checked. It does not usually cost a lot, so you don't have to worry about the expenses. Besides, this can be of great help to you, especially if you have no idea on how to assess problems on the motor. Who knows, your blower motor resistor could be having problems you are not aware of.


    Quit playing with the switch.

    There are times when people are itching to press on the buttons and switches on your vehicle the way little kids do when something catches their attention. However, keep in mind that certain buttons, dials, and switches on your vehicle are not to be played with at any cause. Doing so may affect their functionality and, worse, create problems on the vehicle. So if you don't have any reason to switch the blower motor on or off, keep your hands away from it.
