Replacing Cabin Air Filters

The purpose of a cabin air filter is to filter contaminants from the incoming air, protecting the occupants, the interior and the heating, ventilation and air conditioning (HVAC) systems of the vehicle. To maintain their effectiveness, cabin air filters should be changed every year. The first step to replacing a vehicle's cabin air filter is finding it. The vehicle's owners manual can be consulted to find its exact location. In most Ford models, it can be found under the hood in the cowl area. In most Chrysler models, it can be found under the dash. In GM models, it could be under the hood, under the dash or behind the glove box. In Toyota, Lexus, Nissan and most Honda models, it is behind the glove box. Some disassembly may be necessary to replace a filter mounted under the cowl at the base of the windshield. It may require removing a plastic cowl cover. Before removing the old filter, be sure to prevent any contaminants from falling into the HVAC inlet duct by cleaning the area surrounding the filter. If the filter is located behind the glove box, the glove box may have to be removed before replacing the filter. On some vehicles, cabin air filters can be reached from under the dash and pulled out of a slot in the HVAC unit.
