2005 Kenworth W900L HVAC Box Install

In this video, we install a Kenworth HVAC Box (heater box) on a 2005 W900L. This is a plug & play unit, meaning that all the parts are specific to a certain year and model range of KW trucks, making installation quicker and easier.

The OEM cross-reference for this unit is F31-1036-1 and would fit 2002 - 2007 W900, T800, and T600 trucks.

*Evaporator
*Heater core
*Freeze switch
*Appropriate actuator
*Appropriate expansion valve
*Installed fresh air intake with all the internal parts to operate the fresh air door
*Wiring harness
