2017 Verano, 30K miles. The AC air is starting to smell badly. Worst when first starting AC. I took to dealer and was told the HVAC after blow just need to be activated. This feature will keep the blower on to dry out AC evaporator moisture while the car in off state. This problem is address per bulletin # 00-00-89-027J in SI regarding microbial growth causing odor.

did you replace the passenger compartment air filter at 22,500 miles?
did the dealer check if the AC drain is blocked?

Yes, brand new filter, AC drain good. I was told the smell will gradually go away after a short while.

why do you think the blower will continue to run after the car is turned off, that would kill the battery?
try spraying lysol in to the intake duct work in the cowl area.

There is an AC deodorizer on the market that you spray in through the cowling under your hood while the AC is running to disinfect and clear up bad odors. Usually available at retail parts stores
