Tutorial for cleaning your A/C Ducting System and Condenser Coil on a 20162019 Sierra or Silverado. My A/C had a musky mildew smell whenever id turn it on. It would typically last about 2030 seconds and go away but it smelled terrible. I finally decided to do something about it.

Tools:
AC Pro Vent and Duct Cleaner
Lysol Disinfectant
T15 Torx
