Step-by-Step Instructions
Follow these steps carefully
1
Park, switch off, and empty the glove box
Park on level ground, turn the ignition off and switch the HVAC fan off. Empty the glove box completely. On 2019-2024 Mazda 3 cars the cabin filter is a single filter behind the glove box, not the two-piece under-dash setup on older models.
🔧 Mechanic's note — Ray Delgado
I have seen plenty of glove boxes still full of manuals and chargers when people start this job, so I always empty mine completely first. A clear box drops further and you will not fight the stops with one hand.
2
Unhook the glove box dampener arm
Open the glove box and unhook the dampener arm from the right side of the box. Let it hang free; do not force it.
3
Squeeze the glove box sides and lower it
Push inward on both sides of the glove box to clear the stops, then lower the box toward the floor. The rectangular filter housing is now visible behind it.
4
Release the housing clip and pull the old filter out
Press down on the clip that secures the filter housing and pull the old filter out by its pull tab. Note the airflow arrow direction on the old filter before you discard it; it points down.
🔧 Mechanic's note — Tom Becker
I always snap a quick photo of the old filter's arrow before I pull it out. On this Mazda the arrow points down, and getting it backwards is the one mistake that quietly kills your airflow.
5
Clear debris from the housing
Pick leaves and loose dust out of the empty housing and wipe it clean so nothing rattles or restricts airflow once the new filter is in.
6
Install the new filter with the arrow pointing down
Slide the new cabin air filter (OEM BDGF-61-J6X or equivalent) into the housing with its airflow indicator arrow pointing down. Push the housing clip back so it rests on the filter and holds it in place.
7
Refit the glove box and test the airflow
Lift the glove box back up until the stops re-engage on both sides, rehook the dampener arm, and close the box. Run the fan through all speeds and check for even airflow and no rattling from behind the glove box.
🔧 Mechanic's note — Ray Delgado
I run the fan through every speed before I call this done, with the glove box closed and my ear near it. A faint rattle now means the clip is not seated, and it is a thirty-second fix.
All Done!
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
⚠️ Common Mistakes to Avoid
- • Installing the filter with the airflow arrow pointing up instead of down.
- • Ordering the pre-2019 filter (KD45-61-J6X); 2019-2024 cars use BDGF-61-J6X.
- • Forcing the glove box stops instead of squeezing the sides inward to clear them.
- • Skipping the debris clean-out, leaving leaves and dust in the housing to rattle or restrict airflow.
