Outside Air Intake
Make sure the air intake, located directly in front of the wind-
shield, is free of obstructions, such as leaves. Leaves collected
in the air intake may reduce airflow, and if they enter the
plenum, they could plug the water drains. In Winter months,
make sure the air intake is clear of ice, slush, and snow.
Cabin Air Filter
