Rubber Weather Stripping

This automotive how-to guide was specifically written to assist owners of the ninth generation (2006 to 2011) Chevrolet Impala in cleaning or replacing the air conditioning system's cabin air filter element.

Owners of other similar W-Body or "W" platform vehicles such as the Lumina, Monte Carlo, Buick Regal, Century, LaCrosse, Allure, Pontiac Grand Prix, and Oldsmobile Cutlass Supreme may also find this guide to be useful.

Unlike many other vehicles, the A/C cabin air filter in a W body General Motors car is located under the front passenger side windshield cowling rather than behind the glove box.

Compatible replacement cabin air filter elements include the Purolator C25245 for about $12 or the Driveworks DW-25245 for about $19 at Advance Auto Parts.

Lift Off Windshield Cowling
The first step is to open the hood of your Chevy Impala and move to the windshield cowling on the passenger side of the vehicle. Grab the thick rubber weather stripping located adjacent to the engine bay and pull it away from the cowling until it reaches the half way point. There are two plastic pop rivet fasteners holding the black plastic windshield cowling in place that must be removed before you can lift off the passenger side cowling piece.

Plastic Filter Cover Removed


 
Under the passenger side cowling piece, you'll find a smaller black plastic piece that covers the HVAC system's cabin air filter element. To remove it, just grasp it on the edge closest to the engine bay and upwards and towards the front of the vehicle. Then pull out the old cabin air filter by using the fabric tag on the front driver side edge. If the filter isn't very dirty, you can tap out any large debris or blow the element our with a wet/dry shop vacuum. If you'd rather just replace the filter, slide the new one in place while with the "Flow" or "Air Flow" arrow pointing down into the blower motor housing.

To complete the job, replace the black plastic air filter cover, replace the passenger side windshield cowling, re-insert the two black plastic pop rivet fasteners, and push the rubber weather stripping back into place. On your next drive, you should notice the HVAC system working more efficiently and the air blowing out of the vents should smell much cleaner.
