How do you replace a cabin filter in 2004 Chevy Impala?
You must raise the hood, and remove the plastic cover on the passenger side next to the windshield. Be careful with the washer hose as it also must be removed from the clips holding it. You can purchase a filter at NAPA :-)
Purchase a Purolator Cabin Filter for your Impala. It comes with complete instructions. The filter is located below the windshield, passenger side. The black plastic cover must be removed to access the filter. You simply raise the hood and remove 3 plastic clips, and the washer hose from it's holders. This will allow you to remove the plastic cover over the filter.
