Diagnosing Common AC Problems

Before attempting any repairs, it’s crucial to identify the root cause of the AC malfunction.

Checking the AC Compressor

The compressor is the heart of the AC system. If it’s not engaging, the system won’t function. Listen for the characteristic clicking sound when you turn the AC on. If you don’t hear it, the compressor might be faulty or there could be an electrical issue.

Inspecting the Condenser and Evaporator

The condenser, located at the front of the car, releases heat. The evaporator, inside the dashboard, absorbs heat. Both can become clogged with debris, restricting airflow and reducing cooling efficiency.

Evaluating the Expansion Valve and Receiver/Dryer
