How to replace the evaporator core on GMC C2500?

As the first step to replace the Evaporator core start by disconnecting the negative Battery Cable and draining engine coolant from the system. First recover both refrigerants then disconnect each heater hose. You need to remove the accumulator and instrument panel carrier with the hvac module drain hose.
