A climate control system of a vehicle includes an evaporator, a first blower, and a first blower passageway that receives air blown from the first blower. The system also includes a second blower and a second blower passageway that receives air blown from the second blower and that is fluidly independent of the first blower passageway. The system further includes a ducting assembly defining a common passageway that receives air from both the first and second blower passageways. The first and second blowers are configured to operate in parallel to deliver air to the common passage and across the evaporator.
