Replacing the Volvo cabin filter and cleaning AC evaporator.
Cabin air filter can reduce dust and debris and particulate matter from the air when you drive. You want to do this filter replacement once a year before the spring.
You can use the AQ1067C cabin air filter that fits the Volvo XC90 2003-2013, Volvo XC70 2003-2007, Volvo V70 2001-2007, Volvo C70 2008-2004, Volvo S80 1999-2006, and the S60 2001-2009.
The cabin filter is located under the glove box on the passenger side. You will need to remove the two screws on the glove box panel. Next you will find the filter housing cover that has four torx bolts that will need to be removed as well. You now have access to the filter housing and can pull out the existing filter that needs to be replaced. Even thought the cabin filter may not seem dirty, it is still a good idea to replace it. Make sure to clear out any existing debris you find in the cabin filter housing. Some use an AC system cleaner foam to clean and disinfect the AC evaporator core. Let it sit for 10 minutes and then start the car and let the recirculation fan run for a bit before installing the new filter. This way you know the cleaner is dry and no residue remains within the AC evaporator core.
Now you can install the new AQ1067C filter. When installing the new filter back in the housing, make sure you notice the airflow indicator arrow pointing towards the passenger seat. Now you can reinstall the bottom panel of the filter housing with the torx bolts. Next fit the bottom panel of the glove box back in place. You may have to work with the kick panel to get the side tabs back in place. Now install the torx bolts to the glove box panel.
