Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Air Distribution System: Notes
The air distribution system consists of:
- distribution housing (1):
- blower fan
- damper
- filter
- recirculation throttle.
- air ducts
- vents.
Three dampers control the outgoing air to:
- the defroster
- the dashboard vents
- the floor outlets.
Fresh air enters through the gap between the hood and the windshield.
After circulating, the air leaves the passenger compartment via the evacuation valves in the cargo compartment.
