Yeah, I took a quick look, but didn't see anything obvious. Where exactly should I be focusing my attention on the plug and cable? Anything specific I should be looking for?

The connector itself is a common failure point. Check for corrosion or loose pins. Honestly, if you're not comfortable with electrical diagnostics, it might be worth getting a workshop to take a look. Could save you a lot of hassle.

Thanks for the advice! Took it to a local shop, and you were spot on – dodgy connection on the AUC sensor. They cleaned it up and replaced a bit of the cable. Cost me 95€, but at least the blower is working again! Cheers!

Could be the AUC sensor. If it's faulty, it can mess with the climate control. Have you checked the cable and plug connection to the sensor? That's a common issue.
