Common Noises from a Car’s AC Compressor

Your car’s AC compressor isn’t a quiet monk. It hums, it whirs, and it can even clatter. But, don’t be alarmed! These sounds are typical, part of its everyday chatter. The clicking noise, however, isn’t part of its normal repertoire.

Identifying Your Car’s AC Compressor Making Clicking Noise

So, you’re sure there’s a rogue noise. Now what? Well, it’s detective time!

How to Pinpoint the Source of the Noise

Pinpointing the source of the noise can be a bit tricky. It involves carefully listening while your car runs and possibly using an automotive stethoscope. Sound like a fun DIY project, or should we call in the pros?
