aircon stopped working Page 2

If your car’s aircon has downed tools, start with the simple stuff before blaming the compressor like it kicked your dog.

Check the fuse/relay, make sure the AC clutch engages when you press the button, and confirm the condenser fan actually spins at idle.

Most no‑cold cases are a refrigerant leak or low gas; oily residue on hoses, a green UV dye trace, or icy/short‑cycling pipes are dead giveaways.

• Blocked cabin filter or weak blower
• Faulty pressure switch or expansion valve
• Worn compressor clutch or serpentine belt
• Blend door actuator stuck on “sauna”

Don’t vent refrigerant—it’s illegal; get a licensed tech to evacuate, leak‑test, and regas, and you’ll be back to penguin-spec chill in no time.
