Nissan Sentra Blower Motor
Signs Indicating Problems with Your Nissan Sentra Blower Motor
As a driver, you do not want your cabin neither too hot nor too cold. The air-conditioning system provides you with your preferred temperature especially delivered by your blower motor. Because ride comfort is a very important aspect in driving a car these days, you should take good care of your Nissan Sentra blower motor. Otherwise, not even your best buddy would want to ride your car. Following are some indicators that you need to take a look at your blower motor:
No air blowing
This can be caused by different issues such as bad resistor, faulty ground, or blown fuse. However, if all these electrical components are good, your thermostat may be clogged. Over time, the coolant on your radiator becomes dirty because of a rusty radiator or coolant tank. The dirt particles can get stuck on your thermostat, preventing coolant to flow through it. When this happens, your automatic climate control system would not allow your blower motor to work.
Blower motor does not work on a particular speed
If you experience your blower motor working on three speeds but does not work on one speed, it may be an issue with your resistor. This part is responsible for controlling the amount of electricity the motor receives in order to provide the desired speed. If one or two of the speeds do not work, the resistor may be at fault. What you should do is check the resistor pack for corrosions and replace the corroded and bad resistor.
When you hear a ticking sound every time you turn your Nissan Sentra blower motor on, the motor may be damaged. This problem is more audible at specific speed setups. The ticking sound is caused by the struggling gears inside your blower motor. When these components struggle, it is a sign that they are not biting well anymore due to wear. When you experience this issue, it is advisable to check your blower motor and replace it if it could not be fixed.
Another sign that your blower motor's resistor has gone bad is the smell of burning plastic in your cabin. This is a sign that your resistor has overheated. This is usually coupled with the malfunctioning of your blower motor at particular speed setups. With this, immediately replace the resistor.
