How to replace the air conditioning evaporator core without HP2 on GMC Sierra 1500?

The first step to replace the air conditioning Evaporator core without hp2 involves uninstalling the hvac module. The hvac module requires removal of itsheat stakes using screwdriver and hammer. Unplug all wires from the Blower Motor as well as the Blower Motor control module and sensors before completely removing all wiring from their retainers. Remove all screws which attach the hvac module assembly if it exists. The Evaporator receives its gasket removed before proceeding to detach the upper hvac module assembly from the lower hvac module assembly. The Evaporator core removal is the next step followed by removal of the air conditioning Evaporator air temperature sensor from the upper hvac module assembly. Before installing the new Evaporator core users should include refrigerant oil. The Evaporator core receives installation in the hvac module assembly followed by attaching the upper hvac module assembly to the lower hvac module assembly before reinstallation of the Evaporator cowl gasket. Fasten the screws inside the hvac module assembly until they reach 2 nm (18 lb in) of torque. Reinstall the hvac module assembly together with the air conditioning Evaporator air temperature sensor.
