air con in car not working

If your car’s air con has downed tools, don’t panic—start with the easy culprits before declaring a state of sweaty emergency.

• Blower works but no cold air: low refrigerant from a leak, a lazy compressor clutch, or a dead condenser fan.
• No airflow at all: blown fuse, dodgy relay, failed blower motor, or a clogged cabin filter.
• Temperature won’t change: stuck blend door actuator or a grumpy climate control module.
• Intermittent cooling: pressure switch or wiring gremlins, often heat-related.

Refrigerant handling needs a licensed tech in Australia, so get it leak-tested and serviced properly; your armpits will thank you.
