GrandlandX AC failure

Sounds like a dodgy A/C compressor relay or maybe even the pressure switch. Have you checked the A/C fuse? Could be something simple. What kind of error code did you get?

Fuses are all good! Error code pointed to undervoltage. So, if it's undervoltage, would that definitely kill the A/C compressor? I'm not too clued up with HVAC systems

Undervoltage can definitely cause weird issues with the A/C system, especially the compressor. It might be a faulty relay or a bad connection somewhere. Honestly, with undervoltage throwing codes, I’d advise getting it checked out at a workshop. Could save you a headache!

Thanks! Took it to the shop, and you were spot on – it was the undervoltage issue messing with the A/C. They sorted out a wiring issue and replaced a dodgy connection. Cost 240€, but at least I have cold air again!
