Why does my car smell like water?

"The odor you are likely noticing is from the condensation produced by the evaporator in your heating and cooling system," explains Jake Fisher, senior director of auto testing at Consumer Reports. "Essentially, water accumulates in that particular area and, when left undisturbed, results in the development of a musty smell."

To eliminate the musty odor emanating from your car's air conditioner, follow these steps:

1. Clean or replace the cabin air filter to remove any trapped debris or moisture.

2. Use a specialized cleaning solution or disinfectant spray to clean the evaporator coil and drain pan.

3. Allow fresh air to circulate inside the vehicle by leaving the windows open or using the vent setting instead of recirculating air.

By following these guidelines, you can effectively eliminate the musty smell produced by your car's air conditioner.

Could the air conditioning system be causing the musty smell in your car?

Individuals who detect a musty smell emanating from their car's AC system may wonder if there is mold present. In all likelihood, the answer is yes.
