Here are instructions on how to replace your cabin air filter in a 2002-2005 Toyota. It is recommended to replace this filter at every oil change.
Things you'll need:
Cabin Air Filter.
1.If your front defroster is not working well, then you may need to replace your cabin air filter. A clogged cabin air filter doesn't allow proper air force, which causes the defrosting to take longer.
2.Open your glove box and remove everything inside. Remove the two screws on the side of the glove box. Once the screws are removed, the box will fall.
3.Remove the filter housing by pulling it back toward you. Look at the arrows to show how the filter goes in its holder. Remove the old filter and replace with the new one. Push the filter housing back in. Lift your glove box and put the screws back in the arms of the glove box and into the screw holes. Tighten and you are done.
