Abstract
A multi-zone temperature control system for an HVAC air-handling assembly in a climate control system on a vehicle includes a cold air supply duct and a hot air supply duct operatively coupled to the cold air supply duct. The multi-zone temperature control system also includes a rear air duct operatively coupled to the hot air supply duct and a temperature blend door disposed within the hot air supply duct to adjust a temperature of air flowing through the rear air duct into the vehicle.
