Your Complete Guide to the Dodge Dart Cabin Air Filter: Replacement, Location, and Maintenance
Replacing the Dodge Dart cabin air filter is a straightforward, sub-15-minute maintenance task that any owner can perform, offering immediate improvements to your vehicle's air conditioning performance, airflow, and the quality of the air you breathe inside the cabin. Located behind the glove compartment, the cabin air filter is a critical yet often neglected component that traps dust, pollen, pollutants, and other debris before the outside air enters your vehicle's interior. This definitive guide provides a step-by-step, year-specific walkthrough for locating, removing, and installing a new cabin air filter in your Dodge Dart, explains the different filter types, details the signs of a clogged filter, and answers all common questions to ensure you can perform this task confidently, safely, and correctly.
Understanding the Cabin Air Filter's Role and Importance
The cabin air filter, sometimes called a pollen filter or microfilter, is the first line of defense for your vehicle's interior air quality. It is part of the heating, ventilation, and air conditioning (HVAC) system. When you run the fan, air conditioner, or heater, outside air is drawn into the system. Before this air reaches the evaporator core (for AC) or heater core, and before it flows out of your dashboard vents, it passes through the cabin air filter. Its job is to capture and hold harmful particulate matter. A clean filter ensures optimal airflow, reduces strain on the HVAC blower motor, protects the more expensive HVAC components from debris buildup, and provides cleaner air for you and your passengers. In contrast, a clogged or dirty filter restricts airflow, diminishes HVAC efficiency, can lead to musty odors, and may allow allergens and pollutants to circulate inside the car.
Signs Your Dodge Dart Needs a New Cabin Air Filter
You should inspect your cabin air filter at least once a year, but certain symptoms indicate an immediate need for replacement. The most common sign is significantly reduced airflow from the dashboard vents, especially at higher fan speeds. You may notice that the fan seems to work harder but pushes out less air. Another clear indicator is persistent unpleasant odors, often a musty or moldy smell, when the HVAC system is turned on. This odor is typically caused by mold, mildew, or bacteria growing on the filter media itself, which is damp from condensation. If you or your passengers experience increased allergy symptoms, such as sneezing or watery eyes, while inside the car, a saturated filter may be failing to trap pollen and allergens. Finally, unusual sounds, like whistling or excessive strain from the blower motor, can sometimes be attributed to a severely restricted filter. The manufacturer's recommended replacement interval for the Dodge Dart is every 15,000 to 20,000 miles, but this interval should be shortened if you frequently drive in dusty conditions, heavy traffic, or areas with high pollen counts.
Locating the Cabin Air Filter in Your Dodge Dart
The cabin air filter in all Dodge Dart model years (2013-2016) is located behind the glove compartment. You do not need to access the engine bay. The housing is designed for owner-accessible service. The process to reach it involves lowering or opening the glove compartment to its full extent. In the Dart, the glove box is held in place by a dampening arm on the right side and a stop on the left. You will need to carefully manipulate these to allow the glove box to hang down freely, revealing the filter housing cover. The housing is a rectangular plastic module, usually white or black, with a removable cover secured by retaining clips or tabs. The orientation is typically horizontal, with the cover on the side facing the front seats.
Step-by-Step Replacement Guide for All Dodge Dart Models
Before you begin, purchase the correct replacement filter. Common part numbers include A1160-CAB (activated carbon) or A1160 (standard particulate) for most model years, but always verify fitment for your specific year. You will need no special tools, though a flashlight is helpful. Ensure the vehicle is parked, the ignition is off, and the HVAC system is turned completely off.

Empty and Lower the Glove Compartment: Remove all items from the glove box. Open the glove box door. Look inside the glove box along the right-hand interior wall. You will see a small plastic damper or strut. This damper has a plastic pin attached to the glove box liner. Gently squeeze the sides of the plastic pin or collar and pull it off the post on the glove box wall. This will detach the damper. Next, locate the glove box's stop mechanism on the left side. This is often a flexible plastic tab or a stop molded into the glove box liner. Squeeze the sides of the glove box near this stop to compress the liner inward, allowing the glove box to swing down past its normal stopping point. The entire glove box bin will now hang down vertically, supported by its hinges, providing full access to the rear wall.
-
Access the Filter Housing: On the rear wall of the dashboard cavity (the wall you see with the glove box lowered), you will find the rectangular plastic filter housing cover. It is usually secured by two or more plastic retaining clips. These clips may be on the top and bottom or on the sides. Using your fingers, carefully pry these clips open. The cover should then detach. Some models may have a simple sliding or locking tab. Pull the cover straight off towards you.
-
Remove the Old Filter: With the cover removed, you will see the edge of the old cabin air filter. Note the direction of the airflow arrows printed on the frame of the old filter. This is crucial for correct installation of the new one. The arrows should point downward (towards the floor of the vehicle) or towards the rear of the car (into the HVAC system). Carefully slide the old filter straight out. Inspect the filter housing for any leaves, large debris, or dirt. Use a vacuum cleaner with a hose attachment to gently clean the cavity if necessary.
-
Install the New Filter: Take your new cabin air filter. Confirm it is the same size and shape as the old one. Identify the airflow arrows on the new filter's frame. It is critical that you install the filter with these arrows pointing in the same direction as the old one. In the Dodge Dart, the standard direction is with arrows pointing DOWN (towards the floor) or TOWARDS THE REAR of the vehicle. Do not force the filter. It should slide in smoothly. If it resists, check the orientation; the frame may only fit one way due to its shape. Ensure the filter is seated evenly and completely within the housing slot.
-
Reassemble: Place the plastic housing cover back onto the opening. Press firmly around the edges until all retaining clips snap securely into place. You should hear and feel a positive click. Do not force it; if it doesn't align easily, ensure the filter is fully seated. Lift the glove box back into its normal position. Reattach the damper arm by aligning the plastic pin with its post on the glove box wall and pushing it on until it snaps. Close the glove box door. The process is now complete.
-
Final Check: Start your vehicle. Turn the HVAC fan to its highest speed. Feel the airflow from the center and side vents. It should be noticeably stronger and free of any previous musty odors. Listen for any unusual sounds; the blower motor should run smoothly.
Choosing the Right Replacement Filter: Standard vs. Activated Carbon
You will encounter two primary types of replacement filters for your Dodge Dart. The standard particulate filter is made of pleated, non-woven synthetic material designed to capture dust, pollen, soot, and other solid particles. The activated carbon cabin air filter has an additional layer of activated charcoal embedded in the filter media. This charcoal layer is effective at adsorbing and reducing gaseous odors, smog, ozone, and some exhaust fumes, providing a higher level of air purification. The carbon filter is generally the recommended upgrade for most drivers, especially those who frequently drive in city traffic or areas with industrial activity. Both types are available from various manufacturers, including Mopar (OEM), FRAM, Bosch, Purolator, and K&N. The replacement procedure is identical for both types; you are simply selecting a different filtration media.
Common Questions and Troubleshooting
- What happens if I install the filter backwards? Installing the filter backwards reduces its efficiency and can cause it to clog more quickly. The filter media is designed to capture particles as air flows through it in one specific direction. Reverse installation may not seal properly and can let debris bypass the media. Always follow the airflow arrows.
- Can I clean and reuse my cabin air filter? No. Dodge Dart cabin air filters are not designed to be cleaned and reused. The media is paper-based or synthetic and cannot be effectively cleaned without damaging it. Attempting to vacuum or wash it will compromise its structural integrity and filtration capability. Always replace with a new filter.
- My glove box won't lower all the way. What should I do? Double-check the damper arm is completely detached and that you have fully compressed the glove box stops on both sides. Do not force it, as you may break the plastic. Refer to your owner's manual for the specific glove box release mechanism for your model year.
- Are there any differences between model years (2013 vs. 2016)? The location and access procedure are fundamentally the same for all Dodge Dart years from 2013 through 2016. The part number for the filter itself is consistent. Always verify fitment with the retailer, but no major procedural changes exist.
- Why is there water or a musty smell after replacement? If a musty smell persists after replacing the filter, the evaporator core (inside the HVAC case) may be contaminated with mold. This often requires a professional cleaning treatment. Water is not associated with the filter itself; a clogged AC drain tube can cause water to accumulate in the HVAC case, which can wet a new filter. If you suspect this, have the AC drain checked.
- How does this differ from the engine air filter? They are completely different parts. The cabin air filter cleans air for the passenger compartment. The engine air filter cleans air for the engine's combustion process. They are in different locations and serve different critical functions. Both should be replaced regularly.
Proactive Maintenance and Best Practices
To get the longest life from your new cabin air filter and maintain optimal HVAC system health, adopt a few simple habits. Run the fan on a low setting periodically, even when you don't need heating or cooling, to keep air moving through the system and reduce stagnant moisture. Use the "Recirculate" mode when driving in heavy traffic, behind diesel vehicles, or in extremely dusty conditions to minimize the amount of outside air (and contaminants) being pulled through the filter. Perform a visual inspection of the filter every 10,000 miles or at least once a year, typically before the summer or winter seasons when the HVAC system will be used most intensely. Keep a record of the replacement date and mileage in your vehicle's maintenance log. By integrating this simple check into your regular maintenance routine, you ensure that the air inside your Dodge Dart remains clean, fresh, and healthy for every journey, while also protecting the longevity and performance of your vehicle's entire HVAC system.
