Pontiac Montana heating, ventilation and air conditioning (HVAC) systems deliver filtered, climate-controlled or vent air to the vehicle’s passenger compartment. Two air filters mounted in the HVAC module assembly filter the passenger and driver sides individually. This increased filtration capacity helps to ensure adequate air flow in excessively dirty conditions. Located inside the glove box, the air filters are accessed and changed with no special tools or training.
