This is a guide on how to replace the cabin air filter which keeps debris and pollen out of your AC system and your nose. I usually replace it once a year after the spring pollen season. All you need is a regular phillips head screw driver and the cabin air filter.
The first step is to identify the 6 screws around the glove box that need to be removed. The filter is located behind the glove box. Start by unscrewing the 3 screws at the bottom of the glove box. Then unscrew the 3 screws on top along the inside of the glove box.
