How do you change the cabin filter on 2003 Avalon?

Answer 1

It's behind the glove box. Open the glove box. On the outer right side of the box, there's a screw holding the damper (gizmo that makes it open slowly instead of just dropping open) to the side of the glove box. Take out that screw and back the damper off a little so it's clear of the mount it's on. Take all the junk out of the box, because it's all about to fall out. Now, put both hands on the outside of the side walls of the glove box up by the dashboard. Push the sides inward until the stops that are holding it up clear the edges of the hole the box lives in. It should now swing all the way down toward the floor, so gently let it do that. The filter is behind a removable black plastic panel at the upper left rear. It's about 1.5 inches high and 8 inches wide. Push in on the ends to disengage it, and pull it straight out (toward the front seat.) You'll now be looking at the back edge of the filter. Pull it out, replace it, push the glove box back up into the hole past the stops so it stays there. Reconnect the damper to the right side, replace the screw, and you're done. They usually last about 15,000 miles.
