Why is my car aircon blowing warm?
Aircon blowing warm is usually low refrigerant (needs a re-gas), a leak, or a failed compressor. Most often it's simply lost refrigerant over the years — but if it's leaking, the leak gets fixed first so the gas doesn't just escape again.
The most common causes
The most common cause — the system has slowly lost gas over the years and needs a re-gas.
Needs re-gasIf it keeps losing gas, there's a leak that needs finding and fixing first.
The compressor is the heart of the system; if it fails, you get no cold air.
Debris or damage at the condenser stops the system shedding heat.
An electrical fault or a clogged cabin filter can also kill cold airflow.
