Common Car Air Conditioner Problems

There are several reasons why your car’s AC might not be working correctly. Some common culprits include leaks, electrical issues, and compressor malfunctions. Identifying the source of the problem is the first step towards fixing it.

Low Refrigerant

One of the most frequent issues is low refrigerant. This can result in weak airflow and inadequate cooling.

Electrical Problems

Electrical problems, such as a faulty switch, blown fuse, or damaged wiring, can also disrupt the AC system.

Compressor Issues
