car aircon not cooling

When your car aircon blows “Outback in January” instead of cool, the usual suspects are surprisingly ordinary. Start with basics: set to recirculate, fan high, and make sure the cabin filter isn’t clogged and the condenser isn’t smothered in bugs.

• Low refrigerant from a small leak; needs a licensed regas and leak check.
• Compressor not engaging (fuse/relay, clutch gap, or a dead compressor).
• Condenser or radiator fans not running, so no heat is shed at idle.
• Blend-door actuator stuck, mixing in warm air no matter what you press.

If it cools while driving but not at the lights, think fans or a tired compressor; if it never cools, suspect charge level or a major leak. Avoid DIY refrigerant kits—illegal here and rough on the system—so book an AC specialist for a pressure test and proper fix.
