Why does my Kia Soul's AC stop working when I turn on my headlights?

I recently noticed that whenever I turn on my Kia Soul's headlights, the air conditioning stops blowing cold air. It works fine when the headlights are off, but as soon as I turn them on, the AC stops working. Any idea why this is happening?

This could be due to a problem with your alternator. When you turn on your headlights, they draw more power from the battery, which puts extra strain on the alternator. If the alternator is faulty, it may not be able to supply enough power for both the AC and the headlights, causing the AC to shut off.

Another possibility could be a faulty AC compressor or a low refrigerant level. When you turn on your headlights, the added strain on the engine may cause these components to fail. I recommend getting your AC system checked by a mechanic to identify and fix any potential issues.

Sometimes, a simple fix like replacing the AC relay can also solve this issue. I suggest consulting your owner's manual or a mechanic to locate and replace the relay. It's a relatively easy and cost-effective solution.
