“I have a 2007 Hyundai Sonata and I am experiencing bad odor coming from the AC unit. It smells very bad when I turn on the AC and at times the unit blows out very warm humid air into the car while the AC is running.

Took the car to the dealer and they told me that it is caused by mold and mildew caused by the moisture trapped in the evaporator. My concern is the mold and mildew that can cause respatory problems for the drivers and passengers. …”
