Astra AC Issue

My 2017 Vauxhall Astra (gasoline engine) with 127221 km has an A/C issue. The air conditioning system doesn't switch on, so it no longer cools. An error is stored. I suspect undervoltage. Any ideas?

I had a similar issue with my Astra's A/C. Check the pressure sensor and AC relay switch first. Those are common culprits.

Thanks. Where exactly is the AC relay located? And did your symptoms match mine?

Yes, sounds identical. The AC relay is usually in the engine compartment fuse box. Honestly, I ended up taking mine to a workshop. Saved me a lot of time.

OK, appreciate the info. Turns out it was a faulty relay and a corroded connection, just like you suspected. Repair cost 240€.
