Is your car starting to smell musty? Have your cabin air filter checked.
The cabin air filter is found in most newer vehicles. It cleans the air that comes into the interior through the heating, ventilation and a/c system. Depending on the manufacturer, it should be changed every 12,000 or 15,000 miles. Refer to your maintenance schedule or owner’s manual. You can also tell if you turn the fan on high and there is more noise, or if your car gets a persistent bad smell.
