We’ll explain the most common reasons why your car aircon might smell like vinegar, so you can address the issue and get your fresh air blowing in no time.

Quick Summary

The main reason your car aircon smells like vinegar is due to the growth of mold.

There may also be too much condensation in the system, or an old and clogged cabin air filter.

Replacing the filter will ensure clean and healthy air is flowing through the system, preventing mold buildup and the vinegar smell.

Why Does Car Aircon Smell Like Vinegar? Causes & Solutions

Mold Growing in Air Vales, Ductwork or Components

Mold can grow inside your car’s aircon system through the air valves, ductwork or components and create a smell like vinegar. This is caused by stagnant condensation over time, and can become worse if the air con isn’t turned on regularly. A professional should check the system with a UV light to spot any potential mold and mildew growth.

Too Much Condensation

Too much condensation can build up inside your car’s aircon system and cause an unpleasant odour. This can be caused by the aircon being used too intensively, or by a faulty seal or pipe.

Clogged Cabin Air Filter

An old and clogged cabin air filter can build up bacteria and cause a stale, vinegary smell in your car. This should be checked and replaced by a professional.

Solutions

  • Clean your aircon system and components regularly with a professional service.
  • Turn on your aircon regularly to stop condensation building up.
  • Install an air freshener to mask the odour.
  • Have your car assessed by a professional technician.
