How to Service an Evaporator Efficiently on Buick Regal?

Starting the replacement of the evaporator core requires the HVAC module assembly removal and complete sealing components. The next step requires separating the recirculation housing from the HVAC module assembly after unclipping the defroster actuator retaining clip to remove the actuator. You must unscrew the upper screws of the HVAC module assembly case to separate it. The user should remove both the lower module case seal and the HVAC module assembly seal before extracting the evaporator core with its accompanying water core filter. Install new upper seals together with a new side seal as well as the water core filter onto the evaporator core when replacing it with refrigerant oil. The HVAC module assembly seal needs to be installed onto the lower module case before placing the evaporator core inside the lower case. Foot of the guide touches its position and the upper and lower HVAC module assembly case joins along with proper 1.5 N.m (13 lb in) torque on upper screws. After assembly of the HVAC module, the installer should first secure the defroster actuator then install the recirculation housing by tightening the screws to 1.5 N.m (13 lb in) before completing the installation.
