Mercedes ML Diesel Blower Motor Issue Resolved

The AUC sensor fault could be the problem. The climate control system might shut down the blower motor. Is the air conditioning sensor showing errors? Check the wiring and connectors first. Loose connections are common. Do you know the error code?

Thanks! I don't have the error code. I'll call the mechanic. Is checking the wiring something I can do myself, or should I take it back to the shop? I'm not very experienced.

If you're not comfortable with electrical work, take it back. Faulty wiring can be tricky. If you want to try, inspect the connector for damage or corrosion. Without the error code and tools, a shop is better. They can find the issue and give an estimate.

Okay, thanks. The shop confirmed it was the air quality sensor cable. They replaced it for 95€ and the blower motor is working. Thanks for the help!
