Where the cabin air filter sits and what it does
The cabin air filter in a 2019 Jeep Cherokee is located behind the glove box on the passenger side. It traps dust, pollen, and other particles from the outside air before that air reaches the cabin through your heating and air conditioning system. A clogged filter reduces airflow, makes your climate control work harder, and can leave you breathing dirtier air.
Most owners notice the problem when the air from the vents feels weak or when the cabin smells stale. The filter itself is a rectangular pleated element about 8 inches by 6 inches, made of paper or synthetic material. Jeep recommends checking it every 12,000 miles and replacing it every 12,000 to 15,000 miles, though that interval depends on how much dust and pollen your local air contains.
Key Takeaways
- The cabin air filter is behind the glove box on the passenger side and takes 10 to 15 minutes to replace with basic tools.
- A replacement filter for a 2019 Cherokee costs between $20 and $50 depending on the brand, and you do not need a dealer to install it.
- You will need to remove the glove box by unclipping it from both sides and disconnecting the stop strap, then slide out the old filter and insert the new one with the arrow pointing toward the cabin.
- Checking the filter every 12,000 miles helps you catch a clogged one before it affects heating and cooling performance.
Tools and parts you need
You need almost nothing to do this job yourself. A flashlight helps you see into the space behind the glove box, and a Phillips head screwdriver may be useful if your glove box has a screw (some models use clips only). The main part is the replacement filter itself.
For a 2019 Jeep Cherokee, the correct filter part number is 68298645AA if you want the Mopar original. Aftermarket options from brands like Mann Filter, Fram, and Bosch also fit and cost less. Most auto parts stores stock them, and you can order online for pickup or delivery. Prices typically range from $20 to $50 depending on the brand and where you buy.
Step-by-step removal and installation
Start by opening the glove box and removing everything inside. Look at both sides of the glove box where it connects to the dashboard — you will see clips or tabs. Press or pull these clips inward to release the glove box from its hinges. Some models also have a stop strap (a small rod or cable) that prevents the box from falling too far open; disconnect this by unclipping it or sliding it out of its bracket.
Once the glove box is free, lower it carefully and look into the opening. You will see the filter housing, which is a plastic box with a cover. The old filter slides out horizontally. Note the direction of the arrow printed on the filter frame — it should point toward the cabin (upward). Slide the old filter out, then insert the new one with the arrow facing the same direction. Make sure the filter sits flat and fully inside the housing.
Reinstall the glove box by reversing the process: reconnect the stop strap, then push the glove box back up and press the clips or tabs until they click into place. Close the glove box and test your air conditioning and heating to confirm airflow has improved.
When to replace versus when to clean
A cabin air filter cannot be effectively cleaned and reused. Unlike engine air filters, which you can sometimes blow out with compressed air, cabin filters are designed to be replaced. Attempting to wash or vacuum a cabin filter can damage the pleats and reduce its effectiveness.
If you find the filter is only lightly dusty and you are not ready to replace it, you can carefully vacuum the surface with a soft brush attachment. This extends its life slightly but does not restore a heavily clogged filter. Once you notice weak airflow or smell, replacement is the only real solution.
Signs your cabin filter needs attention now
Weak airflow from the vents is the most obvious sign. Turn on the air conditioning or heat to full blast and hold your hand near a vent — if the air feels noticeably weaker than it used to, the filter is likely clogged. A musty or stale smell in the cabin, especially when the system first turns on, also points to a dirty filter trapping moisture and odors.
Some owners notice the air conditioning compressor working harder or the engine fan running more often, because the system has to work overtime to push air through a blocked filter. If you have not replaced the filter since you bought the vehicle or it has been more than 15,000 miles since the last change, assume it needs replacement regardless of how it feels.
Dealer service versus DIY cost comparison
| Route | Filter Cost | Labor | Total | Time |
|---|---|---|---|---|
| DIY with aftermarket filter | $20–$35 | None | $20–$35 | 10–15 minutes |
| DIY with Mopar filter | $35–$50 | None | $35–$50 | 10–15 minutes |
| Jeep dealer | $35–$50 | $50–$100 | $85–$150 | 30–45 minutes plus wait |
| Independent shop | $25–$40 | $30–$60 | $55–$100 | 30–45 minutes plus wait |
The job is straightforward enough that most owners save money and time by doing it themselves. You avoid labor charges entirely and can complete the work in your driveway. If you are uncomfortable removing the glove box or prefer professional installation, an independent shop usually costs less than a Jeep dealer for this routine maintenance.
Even if you choose to have the work done at a shop, knowing what the job involves helps you understand why the cost is what it is. The filter itself is inexpensive, but labor adds up quickly at either a dealer or independent location.
Frequently Asked Questions
Can I drive with a clogged cabin air filter?
Yes, but you should not for long. A clogged filter reduces airflow and forces your heating and cooling system to work harder, which can strain the blower motor over time. It also means you are breathing dirtier air. Replace it as soon as you notice weak airflow or odor.
What if I cannot get the glove box clips to release?
The clips are usually plastic and can break if forced. Look carefully at how they are designed — some require you to push inward while pulling the box down, others require pulling the clips outward first. If you are stuck, consult a YouTube video for the 2019 Cherokee specifically, as the exact mechanism varies slightly by trim level.
Does the arrow on the filter really matter?
Yes. The arrow indicates the direction of airflow. Installing the filter backward reduces its effectiveness and can allow unfiltered air to bypass the pleats. Always match the arrow direction to the old filter before you remove it, or note which way it was facing.
How often should I check the filter if I drive in dusty conditions?
Check every 6,000 miles if you regularly drive on unpaved roads or in areas with high pollen or dust. Standard intervals of 12,000 to 15,000 miles explore to normal highway and city driving. Frequent short trips in urban areas may also require more frequent checks because stop-and-go traffic pulls more air through the filter.
Is the Mopar filter worth the extra cost over an aftermarket brand?
Both work well. The Mopar filter is the original equipment part and carries Jeep's warranty, but quality aftermarket filters from Fram, Mann, or Bosch perform similarly at lower cost. Choose based on your budget and whether you prefer the assurance of the original part.
