Car AC Smells Bad? Quick Fixes to Eliminate Foul Odors and Improve Air Quality

• Foul smell from car AC indicates mold, fungus, and bacteria accumulation due to moisture in the evaporator core.
• Blocked drainage tubes prevent water from exiting, leading to moisture buildup and bacterial growth.
• Change the cabin air filter regularly (every 20-25 thousand kilometers) to improve airflow and reduce moisture.
• Clean the evaporator core with a special foam cleaner to destroy mold and bacteria if the smell persists.
• For strong odors, consider ozone treatment to completely eliminate odor-causing bacteria from the AC system.
