Where is the cabin air filter for a 2003 chevy s10

SOURCE: where and how to change cabin filter chevy equinox

Hiya...the cabin air filter is located below the front passenger/windshield area.
It's only accessible by standing outside the Equinox with the hood open.
Here's how to do it...(before you pop open the hood)

1) Stand outside at the front-right door area.
2) Just below the front windshield area, pull up a few small black plastic clips that's on the black windshield wiper cowl area- a small flat screwdriver or a special clip-remover tool is handy.
3) Raise the hood up.
4) There may be a triangular-shaped hard foam sound damper at the left side nearby the hood hinge...pull it off if it allow you to work around it with ease.
5) Continue to find a few black plastic clips around the black windshield wiper cowl area.
6) Gently pull up the black windshield wiper cowl cover with care not to bend it too hard during removal.
7) You should see the cabin air filter inside that's held in place by a black rectangular box inside.
8) There's 2 black tabs that holds the cabin air filter in place.
9) Insert your finger or tool to pry the cabin air filter away from the tabs.
10) Remove old cabin air filter.

Remember to reinstall the clip parts back into place when you're finished.

You should get instructions on where to put the air filter when you purchase new ones.  I think that it is under the dash on the passenger side.  There should be a cover underneath the glove box with screws holding it in place.  This thing takes two air filters so Chevy can milk more money out of you.
