PROBLEMS — AIRCON

Car aircon not cold?

A car aircon that blows warm or only cools while moving usually has a specific, testable cause. Here are the most common ones.

Common causes

01

Refrigerant leak

Low refrigerant almost always means a leak somewhere in the system.

02

Cooling fan fault

If it's cold on the highway but warm in traffic, the condenser fan is a prime suspect.

03

Compressor not engaging

An electrical, clutch or pressure switch fault can stop the compressor.

04

Blocked condenser or cabin filter

Restricted airflow reduces cooling performance.

Questions owners ask

Is it safe to keep driving?
Usually yes, but a failing compressor can get worse. Get it tested before it becomes a bigger repair.
