generation 1 crv you remove glove box door 2 easy bolts then remove plastic panel on right 1 screw then remove one plug and 4 screws on right edge of center dash panel that allows yoyu to bend center panel back enough to get to the 3 bolts on that side then three bolts on right side to drop metal bar that glove box door mounts to. then its relocate a wiring bundle and remove remove a lil cover and replace element in frame and reverse. newer ones are much easier. its about 1/2 hour if you've done it before
Sheesh! What a bother.
'06 Toyota Corolla: Open glove box. Push sides toward center to remove box. Push latches on filter cover. Remove cover. Remove filter. Reverse to install.
If you're slow, it'll take 60 seconds. Fast? 15. No tools needed, and I didn't look in the manual. Had never done it before but a cousin said it should be behind the glove box.
Mine had several dead (pinky) mice and the nest on top. It smelled really, really bad, since it was in July...
