Cabin Air Filter Installation
Annoyed with all the pollen and dust in your interior? Unless you special ordered it, Ford left out the cabin air filter. Here's how to install one in your Focus. Compliments of myFordFocus.com Forum Member: CinnabonBoy Cost: $10.00 Time to Complete: 10 minutes Tools Required:

• Flat Head screwdriver
• Phillips head screwdriver

• Purolator cabin filter: C25387 -OR- Motorcraft cabin filter: FP38

1. Stop the windshield wipers when they are in the up position. Since the filter will be placed on the passenger side, this will make it easier to access the panel.
2. In the center of the windshield, there is a small plastic circle piece. Pry it off with the flathead screwdriver, and set it aside in a safe place. Remove the screw you have uncovered. (See picture) This will make it easier to remove the panel you are about to remove.
3. There are 3 plastic locking clips holding the cover down. Use your flathead screwdriver to GENTLY pry them up. Once they are up, give the whole piece a little tug up and to the left. You will see the slot where the filter goes.
   • BE CAREFUL!!!! Everything is made of plastic, and everything can break. Take your time, and don't get frustrated.
4. In this slot, there is an eggcrate style plastic piece retaining the space where your filter is about to be placed. Pull up and out on it to remove it. You will not need this piece, so you can discard it, or keep it in a safe place.
5. Remove your filter from the box.
   • Note: which side is to be placed "up".
6. Slide the filter into the casing, ensuring a snug fit.
7. Replace everything you removed by reversing the steps above.
8. Go in the car, and blast the vent, to remove any dust, etc. that may have been in the vents.
9. Enjoy your clean air! You will notice that your interior will stay cleaner for longer periods of time, and you can breathe easier!!

I just changed the cabin filter of my ES300. I found the instructions on the manual, under airconditioning and audio. It's pretty easy to do. I bought the filter from Kragen's for $21.95.

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.

1. Open glove box
2. Unhook elastic retainer on right side
3. Locate the two "stop tabs", one on the upper left and the other on the right side. Push both to the left to clear their stops and the glove box will swing down, allowing access to the filter cover.
