Most likely, they will have to remove and clean the evaporator core to properly remove the mold smell, since the disinfectant spray didn't solve the problem. May want to ask them to install the optional interior air filtration system, part #82206886. From the picture below, it is the filter at the top. Cost is about $15 for the part.
Here is a do it yourself method from AllPar to solve the smell problem:
David Ta wrote: I am convinced the evaporator design having horizontal fins is the root cause of the AC musty/stench smell on first startup, which will fade out in a good few minutes. ... So, the real cure is to install an OEM evaporator having vertical fins to drain off the condensation, IF there is such one in the aftermarket for any model having this AC smell problem. Or you can modify your car to allow water shedding off easily. An old colleague in the office confirmed that he got this problem with all his recent cars, including Chevy, Ford, Chrysler. Every year, he mixes water and baking soda and poured it into the drain area next to the firewall, rinsing it later with a water hose.
