Where is the HVAC system on a tundra?
The HVAC system is comprised of a “heater housing” under the dash in front of the center console. This box contains heater core, 4-5 servo motors for various blend doors depending on trim level, and AC evaporator with a wing leading over to the blower motor and AC amplifier above the passenger footwell.
