This is a complete rebuild kit for 3rd Generation (02-09) Dodge Ram trucks to fix your heater and air conditioner. This kit will replace all 5 doors in the HVAC box with CNC machined solid aluminum replacements.  This kit includes a Recirculation Door, 2 Blend Doors, a Panel/Floor Door, and a Defroster Door. You can finally permanently fix your heater and your AC doors in your Dodge Ram truck!

This is only for a limited number of people.  It will ONLY fit Mega Cab trucks that are equipped with the rear vent system.  These will be the vents that are in the bottom rear of the center console or center jump seat that are designed for the rear passengers.  No Single Cab or Quad cab trucks have the vents and not all Mega Cab trucks have this option. This kit includes a very specific driver for the defroster door, an extra linkage rod, and an aluminum cam gear to control the rear vent control door. Please note: this will re-use the original plastic rear vent control door that is unique to the rear vent equipped trucks.  This door is not directly driven by an electronic actuator and does not seal against any surface in the box. Therefore it has an extremely low failure rate and is not worth the added cost to replace.

This kit will fit 2002, 2003, 2004, 2005, 2006, 2007, and 2008 Dodge Ram 1500 trucks. It will also fit 2003, 2004, 2005, 2006, 2007, 2008, and 2009 Dodge Ram 2500, 3500, 4500, and 5500 trucks as well as the 2007, 2008, and 2009 Sterling Bullet trucks. 

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.
