Variations Explained
Single Zone/Dual Zone
The "Single Zone" function is for trucks that control both the driver and passenger side temperature control together. The "Dual Zone" function is factory upgrade that allows the driver and passenger side temperature to be controlled separately. It is not possible to simply install the Dual Zone doors into a Single Zone system in order to upgrade to a Dual Zone system. The 4th gen trucks only have the two box choices. If you have a truck with rear vents, the only difference is the duct work.
