The air conditioning filter in the Fiesta is located on the left side under the passenger seat. During the operation of the car's air conditioning system, air flows through the blower, the evaporator box of the cooling system, the small radiator of the heating system, and the air ducts. Whenever the air conditioning system blower is turned on or the air intake mode is set to recirculation, air will enter the aforementioned systems, regardless of whether the cooling device is in use. The Fiesta is produced on Ford's B3 platform. In terms of body dimensions, the car measures 3980mm in length, 1722mm in width, and 1470mm in height, with a wheelbase of 2495mm. The Fiesta is equipped with a 1.5-liter engine, delivering a maximum power of 76 kilowatts and a maximum torque of 138 Newton-meters.
In the Fiesta, the cabin air filter is usually hidden behind the glove compartment on the passenger side. From my experience, you need to open the glove box and check the bottom or sides for small clips or knobs. Press them gently to remove the entire glove box. Behind it, you’ll find a rectangular filter housing—just pull it out firmly to remove the old filter. When inserting the new one, make sure it’s oriented correctly to avoid installing it backward. As for tools, you hardly need any professional equipment; a screwdriver or even your fingers will do. The whole process takes no more than 10 minutes. I recommend replacing it every 15,000 kilometers or once a year—more frequently in areas with poor air quality. Otherwise, the AC may start blowing foul air, and dust and bacteria can accumulate inside the car, affecting respiratory health. DIY replacement is much cheaper than visiting a dealership—the filter itself costs just a few dozen yuan, while labor fees at shops can easily exceed a hundred.
Speaking of the location of the Fiesta's cabin air filter, I've changed it a few times and found it quite easy to locate—it's inside the glove compartment on the passenger side. Once you're seated with the door closed, proceed to remove the glove box by pressing the retaining clips on both sides and carefully pulling it out to avoid damaging the plastic parts. Behind it, you'll find a small recess housing the filter compartment; simply open the cover and pull out the old filter. Beginners might take a bit longer on their first attempt, but as long as you avoid using excessive force, you'll be fine. The tools needed are minimal—gloves and a vacuum cleaner can help with dust removal. It's advisable to replace the filter before spring and summer to prevent clogging from pollen, which can weaken cooling efficiency and increase fuel consumption. DIY replacement can save you around a hundred bucks, and since dealerships often take their time, it's more convenient to handle it at home, ensuring clean and comfortable cabin air.
