Nissan Titan Cabin Air Filter
Finding Out When Your Nissan Titan Cabin Air Filter is Failing
The reason why you are enjoying fresh air inside your car even when the windows are rolled down is the Nissan Titan cabin air filter. It is usually made of pleated-paper, and its function is to prevent pollutants, allergens, and dust from entering your vehicle's passenger area. However, it is exactly this job that causes the cabin air filter to fail. Dirt usually builds up, which leads to the clogging of the filter. The following are symptoms of a bad cabin air filter, which could pretty much help you diagnose or verify its failure:
Change in cabin temperature
You would know that your cabin air filter is not functioning properly when you start to notice a gradual or significant increase in cabin temperature. Usually, the cause of this problem is an overworked air-conditioning system that has a reduced airflow. The temperature tends to rise up some more due to the sunlight's heat, which passes through the window. Inspect the cabin air filter to find out if debris or other substances have accumulated in there, which could have led to the clogging.
Decrease in horsepower
It may not seem like it, but a dirty cabin air filter may affect the engine's performance as well. Because the filter is clogged, the system requires more power from the engine, which causes the engine to mismanage the distribution of energy to the different systems. More power is transmitted to the air-conditioning system, causing the vehicle's operation to suffer. You may also notice a decrease in gas mileage, sluggish acceleration, and hesitation when shifting gears. In this case, you would have to replace the cabin air filter or else the spark plugs might get damaged pretty badly. Over time, leaving your cabin air filter dirty could lead to problems in starting your car.
Excessive dust buildup on the dash
When there is an accumulation of dust in your cabin especially on the dashboard, the possible culprit behind this is a clogged cabin air filter. Take the filter out and inspect if it is clogged, which would require you to replace it. Be careful when you're removing the filter, though. Make sure you don't flip it out or tear it because dirt might fall into the other systems in your vehicle.
