Vinegar – When the air coming from your air conditioner smells sour, like vinegar, the problem could be from an electric motor that is emitting ozone. Other possible reasons could be excess condensation on the coils, a malfunctioning filter, a clogged condensate pan, or mold in the ductwork.
Spray an antiseptic into the exterior air vents (where your car pulls air from outside into the car from). Be sure your AC is set to the setting that pulls air from outside in, so that the spray is pulled into the ventilation system and can directly work at killing of mold and bacteria.
