Seat Leon AC Problem

I have a 2000 Seat Leon with a gasoline engine. The mileage is 89249 km. My air conditioning stopped working recently. The A/C compressor won't engage, and it's not cooling. There's an error code about undervoltage. Has anyone else had this?

I'm not totally sure, but I had a similar issue with my Leon. The air conditioning would cut in and out. Have you looked at the pressure switch or sensor? Maybe a refrigerant leak is causing low pressure, which would stop the A/C compressor from starting. Just a thought.

That's interesting. Can you tell me more about the pressure switch or sensor? Where are they located, and how do I check them for a refrigerant leak?

My problem was very similar. I can't say exactly where the pressure switch or sensor is on your model, but usually they're near the A/C compressor or on the refrigerant lines. I didn't check for a leak myself. Given the error code and how complicated it could be, a mechanic might be best. They can diagnose it properly and check the refrigerant.

The problem was indeed undervoltage, like I thought. The A/C compressor was shutting off because of it. The workshop charged me 240€ to fix it.
