How do you change cabin air filter in a 2002 toyota corolla?

Empty out your glovebox, Everything will fall out anyway. Open glovebox the squeeze the sides together unntil the latches allow it it drop all the way down. You will see a black plastic box about 8" or so long and 2 or 3" in height. That is the case for the filter. You may need a flat screwdriver to unlatch the cover of the case from the clips on the sides..ends, the filter element will slide right out and replace filter and re assemble the same way opposite
