Replacing the Cabin Air Filter in the Vehicle

Model: Mazda 3 MK 1, BK - Years 2003-2009
Part: Cabin air filter

This video illustrates how to replace the cabin air filter in a Mazda 3. The filter housing is located at the lower side on the passenger side. To access it, manually remove the plastic panel that protects it. You also need to remove the plastic panel located at the top. Using a Philips screwdriver, unscrew the screws securing the filter housing cover, then, using a flathead screwdriver, disconnect the electrical connection. At this point, you can manually pull out the two filters to be replaced, one after the other. Now insert the new filters; it is important to ensure the filter is inserted in the correct position, introducing the thin side first, then the thicker side. Finally, reassemble everything by performing the disassembly operations in reverse.
