Not able to identify musty odor in Spark

[zagspark 0]

I seem to have picked up a foul odor somewhere in my 2020 Spark but for the life of me can't find the location or do a remediation. I've done all of the following with some improvement but no cure. 

 

- Baking soda on the carpets and chairs

- Vinegar spray on the roof liner and carpet

- Upholostery cleaner on carpets

- Lysol in the air ducts and from the external intake

- replaced cabin air filter

- washed the engine bay

 

Only thing left is to spray lysol on the door jams and rubber/plastic water drain areas. It seems like its moldy inside. 

 

Any suggestion appreciated!
