Lexus OEM AC System Parts

As you head out for the day, or even a family road trip, you encounter all types of weather. The factory HVAC system in your Lexus car or SUV cools, heats, and ventilates your passenger space during that drive, keeping you comfortable no matter the outside temperature.

How HVAC Systems Work

Heating

Heating is simple. Hot coolant gets drawn from the engine into a heater core. A front-mounted fan blows over the core, sending the warm air into the cabin.
