The cabin air filter on a 2020 Toyota Highlander is located behind the glove box on the passenger side. To access it, lower the glove box, remove the filter cover, and replace the filter with the correct orientation to ensure proper airflow.
Locating and accessing the cabin air filter
Use these steps to locate and replace the cabin air filter in a 2020 Highlander.
- Prepare a replacement cabin air filter that is compatible with your vehicle (check the owner’s manual or a parts retailer for the correct part number).
- Park the vehicle, turn off the engine, and open the passenger-side glove box.
- Gently remove the glove box damper or release the glove box so it drops down fully; you may need to squeeze the sides of the glove box to release the stops.
- Look for a rectangular access door or cover at the back of the glove box area and unlatch it to access the cabin air filter housing.
- Remove the old cabin air filter, noting the orientation of the filter (arrows on the filter indicate airflow direction).
- Insert the new filter with the arrows pointing in the direction of airflow (toward the cabin interior).
- Reinstall the filter housing cover, reattach the glove box damper if removed, and close the glove box.
- Start the car and run the AC on a low setting to verify air is flowing normally through the vents.
The steps ensure you correctly access and replace the filter, maintaining proper HVAC performance and air quality inside the cabin.
Alternate considerations and tips
While most 2020 Highlanders follow this layout, a few trims or regional variations can alter the exact access steps slightly. If you don’t see a rear-facing housing or if the glove box damper is absent, check your owner's manual for the exact instructions for your trim or consult a dealer. For hybrids and some all-wheel-drive configurations, the layout is the same in most markets, but always verify with the manual.
What to know about orientation and replacement timing
Replace the cabin air filter every 15,000 miles (24,000 km) as a general guideline, or more often if you drive in dusty areas or have allergies. If you notice reduced airflow, unusual odors, or increased noise when the HVAC is on, it may be time to replace the filter even if you’re under the mileage threshold.
Summary
The cabin filter on a 2020 Toyota Highlander is located behind the passenger-side glove box. Access by lowering the glove box, removing the cover, and swapping in a new filter with correct orientation. Regular replacement improves HVAC performance and cabin air quality.
