How do you change the cabin air filter on a 2009 Pontiac Vibe?
Open the glove box, squeeze the sides in and remove the glove
box (easy to re-install). Behind you will see a long horizontal
rectangular hatch. Depress the plastic latch and remove the hatch.
Remove old filter, clean out any loose debris, replace with new
filter. Put the hatch and glove box back in and you are done.
