How to replace the evaporator core in the HVAC module assembly on Chevrolet Trailblazer?

The evaporator core replacement process starts with evacuating the HVAC module assembly before unscrewing the assembly halves while accounting for screws that lie beneath the foam insulation. The HVAC module assembly needs separation before removing the evaporator core from its location and extracting the seal between the halves of the HVAC module assembly. Perform the following replacement steps starting with the positioning of the seal within the HVAC module assembly halves and adding refrigerant oil to the evaporator core during its installation when core replacement occurs. After oil addition check the refrigerant system capacities for correct oil amounts. The evaporator core installation into the HVAC module assembly should be followed by the reassembly of the module while the seal must maintain a proper position between the two case sections. The HVAC module assembly halves need to be joined through screw installation at 1.9 N.m (17 lb in) torque and then complete HVAC module assembly installation.
